Post ways to get awesome battery life.

I know everyone is talking about LTE eating juice and whatnot, but I don't think that's the problem. Neither is syncing or whatever. Go to Settings->About Phone->Battery->Battery Use. What's eating up a majority of your battery? At least for me 65-70% of usage is the display. Based on that, it would seem the #1 thing you can do to save battery is turn down your screen brightness. I've got mine set at around 30% or so.

Agreed about the display, but I do not think HTC is the direct problem regardless, but Qualcomm is. OMAP chipsets use dynamic power managment for chipset & radio functions and consistently get better battery life.

If HTC is at fault, it is using Qualcomm chips... Wait doesn't HTC "own" part of Qualcomm in some form or fashion? I guess they are in bed so same fault.
 
Always seems the constant polling from these types of apps can eat more battery than help, but turning data of when the display is off would have to be a net positive.

I ran it for awhile on my Incredible and noticed a little extra but I didn't really like it because I want my data always on . But I did install on my two friends EVOs and they have said they get at least a few extra hours now

I won't be using as like I said I need my data always on for work but I could see it as a big benefit to others
 
What exactly is a bump charge?

From what I've seen, a bump charge consists of:

(optional) Charge the phone all the way up with the power on.
Unplug the charger.
Turn the phone off.
Plug the charger back in.
It will then charge for a while longer... wait for the light to turn green.
Unplug the charger.
Turn the phone back on. It says something like 90%. Whaaa? I just charged it!
Plug the charger back in.

It would seem that the two charging modes on the phone (power on vs power off) don't agree about what they want to do, or what the actual voltage of the battery actually is. You're taking advantage of this and tricking the charger in to pushing another 100-200mAh in to the battery. This should give you an extra hour or so of use, depending on your habits.
 
Having both a Dinc, and my daily user (DroidX), I can tell you HTC isn't very good at building a rig that gets good battery life. Yes, the Tbolt will settle in a get better life as things progress. But not a lot more. The X is hands down a better rig for battery life. Yes, there are tweaks you can do to stretch more battery life. Most of the tweaks are basically shutting off many of the features that make these phones what they are in the first place. That's not an acceptable fix IMHO. I did this the first few months owning my Dinc. Then I said the hell with it, got a 2nd battery, and turned on my features in my powerful smartphone. With my X, I am OC'd and undervolted. I am pretty much a poweruser. I don't use autokiller as I find it is almost better without it. I belive undervolting is a great option for getting more battery life. I don't turn off my push/pull features - in fact I want my phone to push/pull/sync often - THAT's why I have it. It's usually pretty easy to get through an entire (16 to 18) hour day on one charge. Doesn't mean I don't charge it up if I am in a position to do so (better safe than sorry) as I use my phone for more business than personal use. Hopefully the Tbolt will settle into better battery life, some OC/undervolting will help and maybe some good roms will emerge. In any case, I expect battery life will be a frequent complaint of this phone unfortunately.


I fully agree with you , I only had a DroidX for about a week but the battery life was much better stock to stock against the Incredible. I don't ever turn anything off , and I almost always have my screen on max brightness. On the Incredible a simple overclock and undervolted kernal and some setcpu profiles almost doubled my battery life compared to stock . I use mine for busness email but also as my primary music player and I listen to a lot of music . I was getting 20-40 hrs on my Incredible (w/ evo battery) depending on use (actually got 55hrs once but it was very light use )
Right now on my Thunderbolt I've killed the battery off in as little as 6hrs (mobile hotspot for 3hrs and pandora for another 3 streaming bluetooth) and had as long as 25hrs with lighter usage. So far after 4 full days with it the battery life is decent I'm glad I purchused extra kock off batteries and external charger. What's weird is my knock off batteries our out lasting my stock oem battery which is insane comsidering knock off batteries in my Incredible were complete crap

I honestly think once this thing has some good undervolting kernals I think we'll start to see that 20-40hrs of usage easily, I think this could actually eventually get better battery life then a similarly modified Increidble
 
I have tried both Juice Defender 3.2.7 and the beta v 3.3.x. On both, 99% of the options are grayed out no matter what I choose as the profile (default, aggressive, custom, advanced, etc). So I uninstalled it.

My observation is this. On the weekends, my battery life is directly tied to my individual usage on demand as i dont receive too many gmails or sms and phone calls. I go out to the web when I want something. I have facebook syncing only twice a day in general. I use the music app when I want to listen to music.

During the week, however battery life is horrid. I am using Touchdown for exhange to get my corporate email and its set to push whenever something is available. I get tons of emails during the day and the battery constantly drains.

Also, I have all of those other apps that run when I haven't touched them or need them at the time, pandora, cityid, blockbuster, stocks, news, slacker radio. Any ideas on what I can do to improve my battery usage?
 
This is patently false. Different chargers are rated at different mAh. The Thunderbolt's charging port receives 1000mAh from the included wall charger. You should look for a car charger that is rated the same. Otherwise, the phone could be using more power than it draws, especially in navigation mode.

You're confusing total energy (amp-hours) with current flow (amps). An amp is a unit of current flowing *right now*, where an amp-hour is the total amount of current in a battery (or the total amount of current used.)

Chargers can be rated for anywhere from 500mA (millAMPS) to 2000mA. (The iPad and the Galaxy Tab use USB chargers but require 2000mA.)

Pretty much all generic chargers are rated for 500mA per-port, but there are more and more dual-port and even quad-port chargers showing up on the market. The dual-port chargers are equipped with a 1000mA regulator, so they can charge 2 devices at 500mA each, or they charge one device at 1000mA.

mAH, or milliamp-hours is a rating of current over time. If you put 1000mA through a circuit for one hour, you have transferred 1000mAh of energy. Your electric company bills this way: you get charged for watt-hours of energy.

To summarize:
voltage is like pressure. It's how much "push" a power source has. ALL USB Power sources are 5 volts.
amperage is the current flow. That's how much current is flowing right now. Most USB chargers are .5 amps or 500 milliamps per USB port
an amp-hour is a measure one amp over the course of one hour.

Buy this 2x 1500mA Battery+Desktop Charger fr HTC Thunderbolt 4G - eBay (item 230599592281 end time Mar-21-11 17:13:34 PDT)

Charge your battery in the external charger instead of the phone . You'll get an actual full charge probably worth an extra 2hrs of battery life. and have a spare if you can't make it thru the day

Also if you disable News and Stock syncs that will save you battery life and set your screen brightness down to 40-70%

That says "LTE support developed by HTC". So it would seem the Android drivers for the MDM9600 were written by HTC.

Thanks for the reply. I will most certainly look into buying that battery and battery charger. Any worth to the Seidio 1600mah battery?

As for the syncs, My news and stocks syncs are already disabled. Screen brightness is set to 25% using brightness level app. I'll see about getting that battery charger from ebay. I have tried bump charging a couple times as well. I like most users want to be able to use the phone for what it was made for. Thanks again!
 
I got the Motorola Atrix the first day it came out and absolutely loved the phone. It was fast, pretty, and the battery lasted me the whole day. However, after the scumbags known as ATT decided to cap upload speeds (and probably download speeds too on their supposed 4g network), I said FU to them and switched to the tbolt. The speeds on verizon have no equal. They are almost twice as fast as my home internet and the uplaod speeds are probably like 10x faster. It's ridiculous. However, the battery has been less than impressive.

Just curious, when they announce "extended" battery options when the phone first gets released, are those usually the only ones available for the life of the phone or will new batteries potentially be released as well. Why they can't standardize batteries is beyond me (they've already done so with chargers) but it is what it is. The 2750 is outta the question as it is massive and ugly but the 1600 is a marginal 14% increase in output (maybe an hr extra?). Perhaps the quality of the battery is better than the stock battery but even then, I can't imagine it would increase the phone's life by more than 20%. A battery around 1800-2000 would be perfect I think. Motorola did it with the atrix, I'm hoping someone else can help out HTC. Anyone think this is a possibility in the future or just wishful thinking?

I completely understand ... I don't see the point in spending $50 for only 200mah more that's not very much . I'd rather spend $10 on the external charger and another $15 for a OEM battery and alternate them .

I use my phone all the time it's my main music player, i use bluetooth music, pandora, phonemypc, camera, multiple emails syncing , etc. I also leave my brightness on 100% as I want to see my screen perfectly at all times.. I was concerned about battery life so I ordered those batteries and charger about a month before I even got the phone and I'm glad I did.. And shockingly the batteries that came with the charger are out performing the OEM battery . I'm getting about 12-15hrs each battery charge

I doubt it , there just isn't enough space for a bigger battery . 1600mah is as big as it's going to get . I refuse to put the hump on the back of my phone. But as with the EVO and Incredible which the extended batteries were awful huge humps as well. Some hong Kong comapnies came out with Generic extended batteries with a non hump , while the design of the Thunderbolt will limit what they can do I bet there better then the back HTC made for there extended battery

Once this phone has a good undervolted kernal you'll be able to get 20-40hrs easily out of the stock battery I can almost guarentee it

You know what they say, once you try the hump you never go back :)

Need the hump for the Inc or not a whole day of heavier use (when needed).

Still say that considering the best you normally get from bump charging is full capacity, you are STILL dealing with a 1400mah battery. Claims of damatic battery life improvement seems not logical to the battery size.

Just looking at maybe an 8% improvement, if the charge gate opens circuit at about 90% and bump charge gets you to 100% (1400mah).
 
Depressing to say the least. The battery for the atrix was smaller than the one in the tbolt. Sense is ages ahead of Motoblur but HTC completely noobed it when it came to the battery. I think I will grab the 1600 and just pray for the best. 2750 is probably more than I'd ever need in a day and the big case is just too much for me to handle. 1900 like the atrix woulda been perfect. Oh well.
 
I'm up at 2:15am to work. Emails sync every 1 hour, 30 minutes on weather. 4 calls, 15 texts, plus internet. so far I have 13 hours on mine with 67% batter left. I use no-lock app from market and turn screen off immediately after I use it instead of let it time out. Loving the battery life of mine. Great forum lots of info. Thanks to all of you!

This usage is representative of my routine. I have been playing more (learning android and downloading and changing settings) and still getting the pretty much the full day. I have taken lots of notes from people here: running task killer (not on auto - only manual) using power control widget to toggle unnecessary radios and lower screen brightness, adjusting polling email according to priority, bump charging for these first few days (think that will be totally unnecessary once I get a stand alone charger - unsure about the cheap one linked on ebay - probably get the OEM dock when it comes out), using weather only as needed and even then polling only once or twice/day, etc. To my mind, power management is kind of common sense - I just have to learn Android enough to figure out best ways to do it. Just because the phone CAN do a bazillion things, does not mean they all should be running simultaneously.

Just like over-taxing anything - capabilities vs efficiency are never equal. 1400 mAh is 1400 mAh. However, while I do not want/need the big batt, I will have the stand alone charger and carry a fully charged spare batt whenever I think I might need one (if that becomes every day - so be it). This 4.3" screen and functionality are awesome.

As for the demands of 4G, well - I don't have any 4G signal for 100 miles so it is not much of an issue. But, I have to say that 1800+ down and 900+ up consistently on 3G is faster than my Qwest DSL at home and plenty fast for me. When I go into a 4G area, I can always toggle 4G back on (Phone Info app is great for that).

I appreciate how people feel this is a 4G phone and theoretically "should" be able to run all this stuff all the time but realistically, it is the first VZW 4G phone, the network is new, the screen is huge and running all this stuff drains batts. "Should" it be better? Perhaps, but it is what it is and what it is blows the doors off my BB Storm that I was paying the same monthly dollars. Moto Blurr? No thanks. iPhone at $50 less and same monthly? Nope.

When EVDO first launched - the first Evdo phones were constantly searching for EVDO signal and that was fast draining batts too. Many posts sounded just like many of the complaints I am reading now. It got better.

Overall, for me, this is so far great. Is it for everyone? Obviously not but people trashing the phone based on batt life makes little sense to me. If their needs are greater, get a bigger batt or carry two batts or get a different phone. It meets my needs and apparently many others are satisfied too. So, while it could be better, and I imagine there will be updates and better future models, this one is what I anticipated so far.
 
This same logic ties into the mythical "bump charge" method. Folks claim far greater battery life, when all a bump charge does (if anything at all for a particular device) is compensate for the normal charge process cutting of a complete capacity charge of the battery. Considering standard step thresholds for triggering a charge gate circuit can result in a battery being turned off of charging at 90%, there is about a 10% more mah to yield.

Without bump (assuming it works for your device) a 1400mah battery may be charged to 1300mah

After the bump process you would have 1400mah

How in the heck does an 8% charge improvement result in dramatic battery life improvements? A lot of folks seem to really like sugar pills :)

I have never bumped either of the HTC phones I have owned (Inc and Eris) and, even though they are notorious for bad battery life, I have never had a problem with either. I don't turn ANYTHING off (other than the news and stocks, since I'm 20 and have no money in the market, I would say thats a reasonable sacrifice no?) and right now, at 8 hours use, my Inc is at 67% and this is with a battery DRAIN that I can't quite hunt down. I have my Gmail pushing, my Texas Tech email pushing, Facebook for HTC Sense syncing once a day, Facebook syncing every 3 hours and notifications turned on, and sending/recieving 100-200 texts a day. Same thing when I owned my Eris.

Either:
A. Some people sit around with their phone on (meaning display) every second of every hour, never conversate with another human being in person and then question why their battery dies in 6 hours (DUH!).

Or:
B. The more likely scenario is that most of you with terrible battery drain live in horrible service areas, whether that mean LTE or regular CDMA 3G. The radio in a smartphone is, hands down, the absolutely worst battery drain and bad signal areas will exponentially increase this drain.

For example, at school I never get worse than ~80-85dbm signal strength and I never get less than 24 hours of regular use (outlined above) even with this strange battery drain. However, at home, I rarely get better than a ~95dbm signal and my battery is lucky to last past 10 hours of regular use.

You cannot expect to sync everything under the sun every 5 minutes, play Angry Birds constantly, browse the web and never shut the display off and get good battery life, I don't care what phone you're using. Just as such, you cannot expect to take an LTE phone out of good LTE (or CDMA if that is the case) signal and expect the battery life to be good, it just will not happen. Some of you need to reevalute what you believe to be good or bad battery.
 
This is my first droid and htc phone, I replaced a Blackberry.

Do you keep your phone charging all the time while you can? With the BB, I only charged it overnight.
 
i charge when mine gets to around 20-30% or overnight. just depends on my daily. My inc would make it 1.5 days before a charge sometimes
 
I'm also coming off the Droid Eris, and I can't complain about the battery life. I turn off all the crap I don't use (Stocks, Weather, News) and avoid ever trying the bloatware so it has no reason to run. I've altered my brightness, time-out time, and eliminated the HTC time/weather widget. I may also turn off Auto-sync if I have any issues. I will have to remember the Always on Data trick though, that would be helpful.
I don't use a task killer, just occasionally go in and force close those apps that shouldn't be running. I also clear the cache at the same time.

This phone has been amazing for me. Ok, it's a bit bigger than I'm used to, but the speed of the phone makes it all worthwhile.
 
If your phone lasts, let's say 6 hours as you said your Thunderbolt does. And you have a 1400mah battery, which the stock battery is.
You are getting roughly 26 minutes per 100mah. So if your battery was 2000mah, it would only give you 2.6 more hours, bringing you to a whopping total of 8.6 hours of battery life. And it would also make your already heavy-huge phone even bigger and heavier.

Maybe it's not the size of the battery that is the problem.

The Extended battery may also be more efficient/ handles the demand better. For Whatever reason.. My extended battery is lasting forever...

So far it's 18Hours, 21 Minutes since Unplugged... and is sitting at 56% battery. There is idle time in there as I was sleeping for 6 hours...but I never turned off GPS or 4g or Syncs. Navigated for about 45 minutes...checked gmail... made a few phone calls... texted a few times... took a few pictures... Epic.

The original battery would've died at say 8 hours max. So far i've gotten more than double... and still have 56% to go.

I charge my phone every night, over night. I learned from my Incredible that if it gets off of its cycle, it gets b****y. :) If I'm using my phone for music (plugged into my speakers at home/in the car) for an extended period of time, I might throw it on the charge for that.
 
Weather Bug Elite was killing my battery because I had it set on using "My location" and auto-updates. It would turn on the GPS, and because I was indoors, would keep the GPS on forever trying to find my location. I changed it to check weather on a location I have put in (no GPS), and only to manually update.
 
Just for kicks, I did a factory reset and haven't installed anything on my phone at all. Have had my phone on for 5 hours now with mild-moderate use (texting, email, internet, music) and I am at 85% battery. It's clear to me apps destroy your battery life. Not sure which one, but just what I've discovered.
