Possible battery fix from HTC!

[trance2002]

I have had the same fast battery drain issues as many. I have been trying tweaking data settings and running the overclock widget without much success. I did a few things yesterday and today I finally have a useable battery life. Problem is I don’t know which one is actually responsible for the improvement or if it is a combination.

I did the on and off recharge from this post enough times that I lost count. I never had it be green the moment I turned off the phone. At the end there was always a couple of minutes of amber before it went green but the first couple of times I turned off the phone it was 10 minutes of amber so the duration did get shorter. Maybe that did something.

The other thing I did was have the task manager start aggressively killing idle processes. Before that I just let them run because of things I had read about not needing to kill things in Android. Even though I had my sync settings at 4 hours across the board for anything going out to the internet, I suspect news widgets and such were draining the battery with persistent connections. I can’t prove that but now that I have anything idle getting killed I am getting good life.

Finally I disabled Background data. The only thing I have found that asks me to turn it on so far is the Market and I just disable it again when I’m done there.

Before the changes I would lose 20-40% during the 8 hours I slept. Last night 9%
Before a 20 minute TED video would eat 20% of battery, today 6%
Before a 20 minute video stored on my phone 15% today 4%

I wish I could say which one of these has done the trick but if you are having problems, give them all a shot and maybe it will work for you. I’m glad I can finally enjoy the phone.

my apologies, was hoping you'd say yes, because that's what i did, i was hoping you'd be the lab rat and test out the battery first.

Just for fun being a brand new sprint user i have been calling sprint tech support about this and have gotten the usual blah blah its a superfast phone and you can run lots of apps...

So nothing of any value there...

i do have to say.. inserted fully charged tp2 battery this morning and have been texting and surfing for 3 hours with only 20% usage of battery... so i am really begining to feel it is a charging problem....

I did this last night. I also did about half of the other non-root/OCW tips I have seen on here in the last 24 hours. (Wish I could list them all, but mainly tried to turn off everything that would be using the radios and data while the screen is off. I have ATK set to aggressive, turned off Google talk, GPS, no 4G area, etc.). I started with 100% @ 9:00am. I used the phone for 42 minutes straight (web mainly) and went down to 82%. I turned on my computer and set the phone aside for an hour and 15 minutes. Received a couple emails for my amazon evo case orders and still have 81%. So 1% drain in an hour of standby, screen off state. I'm on an airrave and get generally bad signal at home, so 18% for 42 minutes of pretty much continuous web usages doesn't shock me (comes out to about 3.75 hours of continuous usage per charge).

I think this will work, though will take any more improvement that HTC/Google want to deliver via update.

the trick did not seem to work for me

its working for me wowwwww

works for me. It's been unplugged for 15 minutes an only dropped 2% while I have been online. Before the on off trick 15 minutes would drop 12%...I never got the light to stay green right after turning off but it did get shorter to get fully charged while off.


Ok so I'm back an my battery level still sucks. This only worked last night. I did the same for my girls evo and left it unplugged and it ply dropped 4%. Considering my evo now is back to draining the battery quick. I have lost hope. I have done most of the tips every one Has suggested

thing is when u first get the phone you shouldve turned it off and charged all the way then used it untill dead and repeated the process at least 1-2 more times to break it in but since none of us could wait to get the damn phone outta the box we prob didnt do these things and now we are stuck with crap batteries but i will try this method and report back

Same here, I work for 8 straight hours and when I get home I still have over 50% battery, no complain about it, I'm very satisfied with the battery life.

There is an issue with the charging circuit for the EVO 4G. Let me explain what my phone is doing. I drained it down to 3% and charged it with the phone on, but a strange thing happened. After about 2 hours, the display light up and the LED was still amber in color. I checked my battery status gauge, and it said 97% and battery was discharging. What the hell? So, I proceeded to restart my phone and sure enough, it showed 100%, but rapidly dropped to 97%. I proceeded to plug in the charger and after 8 minutes, it showed 100%. Afterwards, my phone stayed at 100% for 15 minutes. Next charge cycle, I'm going charge the phone with it off and see if anything strange happens on start up. HTC better fix this issue because of alot people probably think they have a bad battery, but it's probably not getting fully charged.
