Battery problems, quirks and issues: Read first.

yeah, I get those random reboots when it gets below 15% or so... it doesn't do a complete reboot, though... and when it hits 3% is when it shows the red battery with a line across it... I have a batter graph running in the background, so after a full week, we'll see how it starts cycling... as of last night, took about 6 hours to discharge and 1.5 hours to charge the battery...

ok.... I've been off of the charger for almost 6 hours and I'm only down to ~70%. This is much better than the past two days. And still with the moderate/light heavy usage (ring volume, texts, alarms, email scans every 15 mins, etc etc etc) It's still a little annoying having a battery die so quickly but it is an improvement, assuming the conditioning is working.

Just a note: But if you guys/gals really want to make a meaningful comparison on battery usage - YOU MUST ALL have the SAME setup (settings + programs + alarms + volume settings....etc...) on your phones, as well as take the same routes every morning.

In regards to the keyboard lights going off at 15% and below - maybe it's time to generate a STICKY of what we want for the next update.

I think most of us are just sharing experiences with each other and as a community to confirm that it's not necessariliy the battery as much as the way the phone does the battery meter. I am only guaging my performance against my own previous results. I'm pretty sure most people here realize that one persons experience will not be the same as anyone elses.
 
Graph data over 15 hours (looks like it would have made it 16?) I plugged it into the charger when I went to bed:

graph.jpg


Charge % on the y axis, time in h:mm on x axis. Sorry for the weird formatting, I'm not used to excel 2007. Samples came in 5 min increments, and trend line is logarithmic... just seemed more helpful than a straight line. If not, oops. You smarter people can still glean some good info from the graph hopefully :p

Data is from the battery graph app.

Edit: oh, right. Um, I used phone apps throughout the day, along with internet + voice calls. Active GPS was off, along with wifi and bluetooth. Today I'm running the phone with GPS set to active, but battery behavior seems to be the same.
 
I have read this thread from beginning to end, and I would just like to share my thanks and gratitide to Satinkzo... You are the person that I noticed was the first to share input about this issue being due to the batter meter, and not the battery..
Moreso, I appreciate your very detailed and often (and consistent) updates as to the results of your "experiment".
I just wanted to to take a moment (no pun intended) to Thank You for your contribution to solving this issue.
From the way this thread is turning out, (and from my experience from my FULL discharge and FULL charge last night), I think that we've got this problem resolved! My indicator is showing much more power today at this time than it has previous to my full discharge/ charge.
I am going to do one more full discharge/ charge tonight, but last night when I did my first full discharge I used the HECK out of my phone for several hours on 5%, then 3%... It is my opinioin that if the battery sucked so bad, it would have died much quicker.
Again, Thank You for your taking charge (dammit- pun!) on this issue and your consistent updates..
Just MY opinion, and gratidude- which nobody seems to ever give these days..
 
Hey, thanks for the compliment. Like most, I was just trying to figure it out too and I'm glad this forum is active enough that we had a decent size sample of users to report their findings and that everyone was comminicating often and concisely.

Even though, like you said, it seems we all agree the guage is flakey, I am still making calls to Sprint and Samsung to complain cause I do truly want an accurate meter. But I don't freak out if I look at my phone and see 15% or even 5%.
 
I don't know if it's conditioning or not, but I noticed from the drain-o-meter app that system_server was my most active process. Reading around other forums, I gathered that some people had issues with Google Latitude causing something similar. I disabled latitude and today the battery seems to be holding up better. Maybe it's a placebo effect though.

To the people who have had worse problems with this, are you using latitude or not? I've already noticed that the cell tower triangulation on this phone is buggy, maybe this is contributing to the bad battery life some of us are seeing on top of the bad meter.

I think we're all appreciative of those who have gone above and beyond as we all were experiencing the same problem and collectively working to try and form a solution. Or better said, verify what we all were experiencing. I'm sure the thought of having purchased a faulty device may have overridden the thoughts of those of us who are a little more curtious to the efforts of those who help us. Just MY opinion.
 
Does anyone think it matters if the phone is on or off while charging? I've done at least 2 full discharges. Same as everyone else...I can run forever on 3%. Definitely drops quickly from 100% coming off the charger.

It's really odd that usually if you completely shutdown the phone, then turn it on, the battery remaining will be higher?

It'd be nice to disable the 15% automatic backlight off. But hey...isn't awesome the phone is very usable without any backlight at all!! AMOLED rocks.

I reported the issue to Spring as well.
 
Keith_kris,
Nice find on the latitude and related services. I don't use it, so I never saw anything going on with it, but others may benefit greatly from that info.

As for my report after my 3rd full drain (well mostly full)...

Last night I tried to kill my phone battery for the 3rd night in a row, but had to give up and go to bed. As I reported earlier in the thread, I started after dinner last night, streaming pandora and browsing the web, playing with google sky and various other things. I finally had to give up at 11pm or so with the battery at 3%. It just wouldn't budge and wouldn't shut down. But the previous 2 nights, I worked it over and kept restarting the phone until the battery could barely sustain on time enough to establish service connection.

Anyays, today, phone off the charger at 6:45am again or so.
I used my GPS for about 35 minutes today with sprint nav instead of google maps, did a turn by turn direction with the screen on the whole time.
I browsed the web alot today. Made a few posts on some sites with the phone too.
Made quite a few phone calls, but I do not recall the amount of time total.
Sent/received a handful of texts, but not overwhelming amount
Did an hour of Pandora at lunch
I was also in very poor coverage for most of the day inside a manufacturing facility and generally I remember on my other phones this caused a bit more drain on my phone.

It's now 5pm and battery is at 50%

My plan is not to run the phone down everynight, but I think once a month or so, I will as I did with my touch pro.
 
If I'm not mistaken AMOLED screens make their own light like plasma screens do. They don't use a backlight and then filter it like LCD does which is why they have such an awesome contrast ratio.
 
from what I've read about AMOLED there is significantly less power draw on the battery. I've been off the charger for almost 11 hours now and my indicator says its only at 40% now. By this time the past few days I would have been down to ~15%... Give or take a little bit.
 
Not a good day for my Moment. I took it off the charger at 7am after an eight hour charge. The phone shut off around 11am after the battery went dead. I had two 5 minute calls and 6 text messages. I hardly used the phone. The phone was getting real hot in my pocket. The screen was off but obviously some process was still working. I am now running the drain-o-meter to see what's up. Too bad there isn't a program that blends the drain-o-meter and the Battery Graph program.
 
Took the phone off charge at 9am/100%. By 12:30 I was at 15% and the backlight shut off. The phome remained on and useable until 6:30pm.

However, I don't consider the expereince useable since I had a really dull screen for like 5.5 of 9 hours.

I love the Moment but this is starting to piss me off.
 
Here is some more info on the battery. I have 2 Moments bought on Nov 1st. Batteries were terrible on both the first 2 days and I was very bummed. Then I drained and recharged.

Here is my experience starting yesterday. Short story: phone ran 28 hours and it is still at 15% where it has been for 13+ hours.

Used Battery Graph to get this data. From standard installation, I removed Sprint TV, Sprint Football (I think that is what it was), Weather Channel App.

So basically the only thing I left were shortcuts, not widgets.

Wifi off, GPS on (but nothing using it), Bluetooth off.

Very casual use: a few text messages sent/received, couple of short voice calls, GMail and Moxier Exchange mail running (I run Exchange in push mode 9a-5p and poll every 30 minutes otherwise) with several small emails sent/received.

Thurs 3:30pm 100% (taken off charger)
Thurs 4:00pm 80% (wow, that was quick)
Thurs 7:30pm 50%
Fri 6:00am 15% (so it stayed at 50% for 10+ hours)
now this is the kicker
Fri 7:30pm 15% (still -- usable with full brightness screen)

Now I am putting it back on the charger. Normally i would let it drain more but I cannot afford the time right now.
 
When you say you removed them from the standard installation you mean just removed them from the homescreens?

Yes, just removed from home screens. I don't think you can uninstall those apps (unfortunately).

Even after these are removed, some may still be running so I killed them with TaskPanel at the beginning of this test.

I didnt think there was a way to uninstall them, but I just wanted to make sure.
 
Ok I have passed the 15 hour mark with what I consider normal use:):). I thinks that is great! You just have to get past the lame battery meter. Shows 5% and I bet I get at least another 30min:cool:
 
Quick update on my second day after full charge, these are based on what i observed while using the phone:

8:30-8:40 -> 100%
8:40-11:30 -> 80%
11:30-2:30 -> 70%
2:30-3:15 -> 60%
3:15-6:30 -> 50%
6:30-9:00 -> 40%
9:00-10:00 -> 30%
10:00-12:30pm -> 15% And I've been at 15% since.

Looks to be solid battery life after consistent of phone, playing games, txting, phone calls, and using my gps.
 
Just to chime in on my initial relationship with my new Samsung Moment as far as the battery issue was. Purchased on Nov 3rd, I was alarmed the next day when it was down to 50% before noon.

I turned off GPS, and any automatic background usage by the Google programs. I left wifi and bluetooth on because, well without these, I don't really see a need to have a phone this good. My battery lasted somewhere around 15 hours from an 'all night' charge to completely shut off. When I hooked it up on the charger, I had to unhook it and remove the battery, then put the battery back in,to even get it to turn on..before I got it back on the charger, the battery showed zero percent.

I've just downloaded widgets to turn wifi and bluetooth on/off quickly from my main screen. I'll test that over the weekend to see if there is any significant change in battery life before I make any final decisions.

I like this phone but I may have to go back to my WINMO phone..didn't care for it but at least it made it through the day. Thinking about the HTC Hero but it seems there are problems with it as well according to a quick 'scan' of the 'boards'
 
Dont have the moment yet, but im definitely leaning that way. One question though. When the phone completely dies, will it come back on as soon as you plug it in to the charger? Or does it have to charge for like 10 mins before it starts to boot. When my pre dies, if you plug it in, you have to look at a big battery icon for like 10-15 mins before it even tries to boot. Then it takes like 3 mins to get to the home screen. Its very frustrating.
