[Battery] Fixes and Tips

so after 10 minutes of slightly more intense use than last time, i'm already back to 96%, not sure i'm seeing any gain from this....sigh..... oh well....
 
I
THE EXPERIMENT: I plugged in my phone last night and woke up this morning to a green LED. I turned my phone completely off and plugged it again. Alas, a red LED which did not turn green for another 20 mins. I then unplugged my phone and plugged it back in again; RED LED for another 20 mins! I did the same thing over, in total of 3 times.

RESULT: My battery right now is showing 98% after being off the charger for nearly 2 hours. It used to go to 90% in 10 mins!

.

Thanks Niterider!
I followed your instructions and now my battery is still at 100% even after 10 minutes off the charger! First time ever. Hopefully we only have to do this once and then the battery charges properly after that.

HTC should definitly be made aware.

Cheers,
Teslas
 
I have still a better way to fix your battery woes. Leave your handset plugged in 1 hour after you get the green light. Then and only then will you have a battery with 100% charge in it. These systems are set to go into trickle charge at about 93% of charge to stop over heating and possible fires. It will take another hour to fully charge the battery past the green light phase. Nothing is wrong with your phones people. They just don't want to burn down your house like has happened in the past with Li Ion batteries fast charging to close to a full charge.
 
i have also experienced this problem, and my battery life has been much better once i turned off the phone and charged it again...

now that i have hopefully "fully" charged my phone, should i let my phone completely die to 0% and then charge it fully off again to try and calibrate the phone? hopefully this will resolve the problem?
 
what does HTC consider acceptable then?

judging today from my texting, using facebook for like 10 mins, 10 mins of calls, surfing the web for about 20 mins and downloading an app from the market. I will be getting like 14 hours out of the battery. (7 hours currently since pulled off charger and at 56%)... this is pretty much more than my old RAZR (wouldnt last a work day), way less than my LG VX8300 (usually lasted 2-3 days), and on par/more than my centro (got through work day pretty low or dead by bed).

Is 14 hours acceptable or should I be complaining that I didn't get my day and a half?
 
Here's my theory of what we are seeing:


The phone is ON and plugged in to charge overnight. The battery reaches "full capacity" sometime during the night, hours before we wake up and unplug it. The charger is programmed to STOP charging after "full power" is reached, so as not to damage the battery by overcharging.

Since the phone is still ON and not charging, the battery starts to deplete, but still shows "full power" because it is plugged in. Once it is unplugged, it drops very fast because it was actually NOT at "full power", but something lower.


Now when we plug it back in until it reaches "full power" again, we immediately unplug it and it actually is still at "full power".


This theory could be tested by turning the phone OFF while charging it overnight. If correct, it should not exhibit the same rapid drop off form 100-90% as if it were turned ON overnight.

Actually, I did this last night, and I got the same result as letting the phone charge overnight with it on.
 
Mine might seem a little better but still not great. It was pretty consistent where it would drop to 90% after 10 minutes. After doing these steps i have 95% after 30 minutes.

I wish i could figure out what i did last night. I think i charged it > let it drop to 90% then plugged it back in without shutting the phone off and let it charge till it was green and then unplugged it again.

Last night i got 7 hours with only using 20% of battery. That is something i could live and it keeps me optimistic that this is something that can be fixed now that I know that it is capable of getting that much time with only using 20%

Edit: also i am not to worried about the first 10% only, I am more worried total hours until it completely dies. we might be geting to caought up in the first 10% thing event though it still seems to be part of the issue.
 
last night was the first time i did not lose hardly any charge while i slept. i unplugged it at 98% cause I didnt want to "overcharge" it and when I woke up, i swear it was at 96% 7 hours later and I did not put in airplane mode or turn off wifi, like i have been...it must have been some fluke....
 
I, like many, suffer from battery depression. I've been scouring the forums and grasping at straws to figure out how I can improve battery life without cutting out features. I also ordered a new TP2 battery that should be here in a couple days. But today I decided to try something....

Alas, a red LED which did not turn green for another 20 mins. I then unplugged my phone and plugged it back in again; RED LED for another 20 mins! I did the same thing over, in total of 3 times.

Am I on to something here? I think this is more proof that the battery isn't being charged all the way, perhaps maybe only 70% of it's capacity on the initial charge. I am hoping that the battery "remembers" how full it can actually charge to so that I do not have to repeat all the steps above every time i charge the phone.

I posted this same finding a few days ago, I think there's something with the auto overcharge that isn't letting the phone really charge to 100% that's why people are seeing almost an instant drops from 100-90 and sometimes 80%
 
Could a MOD please sticky this thread temporarily, and maybe add a poll to it so that A. we can get a larger test group and B. so people stop creating more and more threads about batteries?
 
another thought, is it possible that voltage to the battery is a problem? mine is showing 4150 mV after booting up, should it be closer to 3.7?

Thats not the voltage -to- the battery, its the voltage supplied -from- the battery. Also, chances are that the reading you are seeing isn't exactly accurate since it is probably using a low precision ADC to read the output. Maybe someone could chime in, but i dont think that would exactly be the problem
 
I've done this type of charging twice now. While it does take longer for the battery meter to drop from 100-90, I am NOT getting better overall battery life. Same usage as before. I'll get about 3 hrs of awake time before it's under 9%. While the battery meter maybe more accurate, it doesn't seem to extend battery life at all. YMMV.
 
People are way too focused on what % their battery meter says.

You can do all the stuff you want to mess with the calibration of the meter, it's not going to affect how much energy is stored in the battery.

Worry about how long your battery actually lasts, not how quick it moves from X% to Y%.

Although I'm sure this may be true, I have to say that I believe what all the users on the forum have been stating. I leave my phone charging overnight (typically 6-7 hours) and within the first 20 minutes of being off the charger it is down to 92%. You have to accept that not all users are dumbasses and not all issues are user error.

I don't think that's necessary yet since it's getting bumped consistently but that's their call.
I pulled my battery, charged it externally, have phone calls, email, GPS, Wifi, animated wall paper, one hour later... 100%. This is crazy. I'll bet the sensor on the phone is timed to shut off to prevent over heating. Remember those exploding iPods (or i somethings)

I'm not sure what HTC's acceptable charge time is, but in my opinion any phone with average use (a bit of texting, e-mails, surfing the web) should last from the time I take it off the charger until I'm ready to go to bed. I have never had a phone that hasn't been able to last that long...typically around 17-18 hours for me.

That's exactly what I was worried/wondering about ...

have not tried charging it externally as I dont have an external charger, but after 15 minutes of charging to green light while powered off, i'm at 99% which seems to be a slight improvement for the first few minutes, i doubt it makes my phone usage go from 6-10 hours to 12 to 16 hours though....

Been there done that.

I read an article about cell phones and their batteries and found this interesting and I copied and will paste it here.

"An active cell phone is in constant communication with the tower and consumes small bursts of energy once every second or so to check for incoming calls. The transmit power is adjusted to the signal strength. If the cell phone is close to a repeater tower, little energy is needed to communicate. Moving further away or entering an environment with high electrical noise, such as a shopping mall, hospital or factory, more energy will be required. An analogy can be made to sitting in a restaurant. In a quiet establishment the voice can be low, but as the crowd grows, everyone needs to talk louder to be heard.

Living in sight of a tower has advantages and your battery will run longer between charges. In essence, towers are the best friends to cell phone batteries.
"


I understand that a smart phone with added features will use more energy but when an HTC rep tells me she gets a day and a half with her INC and I get 5 hrs something is wrong! Maybe she lives right under a tower.
 
I've been doing the unplug in the morning and plug it back in since the second day I had it. It definitely lasts much longer. I didn't know it was a widespread issue though. Glad it isn't just me but it does suck that I can't just unplug it in the morning after charging it all night and be ready to go.

That's fine and I agree, but if the light is green while the phone is on, why does it go red when turning it off? No unplugging/replugging, just turning the phone off. I haven't experienced this type of behavior with any phone I've owned before.

I agree with you in that the focus should be on how long the battery lasts over the % shown on the display. But getting the calibration right to allow a complete charge CAN potentially have an impact on the total charge on the battery.
