[Q] [Help] My battery is draining too fast, some soft problem ? - Hero, G2 Touch General

I bought this Hero off eBay, and it was dodgy since the begining.
The phone had cyanogen, and was restarting itself occasionally.
So i wiped it, installed 2.1 and it got fixed, but now i have a problem with battery drainage.
Its insance, 10minutes-10% im pretty sure its not supposed to be like that. with or without wifi/3d turned on, its just riddiculous.
I borrowed battery from a friend, and that didint make any change, i installed latest update from the autoupdate in the phone and still its bad. I read somewhere here that its faulty email app that keeps on trying to sync and drains battery, how do i fix that ?
I did a full wipe, cleared cache and everything back to factory settings, with no apps installed it goes from 100% to 0% in an hour.
I downloaded 2.1 from some android forum, as i was unable to find one here (there are only links to 1.5 on the xda.wiki WHY?)
If you can point me to a proper 2.1 (or higher?) software to download that doesnt do this crazy **** i'll be happy as infant on crack.
Please help, here is my software information:
Firmware: 2.1-update1
Baseband version: 63.18.55.06JU_6.35.09.26
Kernel version: 2.6.29-063c4d24
Build number: 3.32.405.2 CL191507release-keys
Software number: 3.32.405
Browser version: WebKit 3.1

Try calibrating your battery it gave me a huge boost on my hero... went from getting 16hours day.. to about 30hours on a single charge!!
Every time you flash a new ROM you need to calibrate your battery. The battery meter in the OS (Android in this case) is generated based on the battery stats file.
Battery stats is erased when you flash a new ROM.
Easiest method of battery calibration when you're intending on flashing a ROM:
Ensure battery is fully charged according to the OS. Switch phone off, unplug charger and plug back in. Once light is green, leave charging for another 30 minutes (light goes green at approx 95% charge).
Switch on, flash ROM. Allow first boot to complete.
Shut phone off. Disconnect charger. Remove battery. Replace battery. Place on charge, light green, leave charging another 30 minutes, yadda yadda. Switch phone on, boot immediately to recovery. Wipe battery stats.
Boot phone up. Now would be a good time to install JuicePlotter. Use as normal. Do not charge, let the battery run down completely. When the phone shuts itself off, power it back on. Repeat process until it won't switch on anymore.
Remove the battery. Put the battery back. Turn the phone on. Repeat until it won't turn on anymore.
Now charge the battery on the mains to 100% while the phone is off, keep charging for 30 minutes after light goes green. Power on. Voila, fully calibrated battery.
The last part, run until completely dead and charge only needs to be done once in a while (this is calibrating the battery innards, not the battery stats)

hah, yea thats what i accidentally figured. phone was switching off, but when i powered it back on it had 30%.. and it was like that 3 or 4 times.
I ran it down completely and now am charging it till max, we'll see what happens. at worst i'lkl start your process from the beginning thx !
I diidnt know you had to do that. i've been playing with my G1 and not even once i had to calibrate that.. maybe i should

How'd it go? Any improvement on battery life?

it diidnt help I did what you quoted step by step and its still running down the battery like crazy :/ what else can i do ? im thinking of switching to 1.5 but thats just not progressive and my friends phone is running fine on 2.1, with the same battery even.
Edit: i've installed task killer and killed all the mail checking apps.. hope that is the problem
Edit2: it didint help at all, in 5 minutes i lost 15% fcuking hell !

I just switched to 1.5 and its still happening ! I using a different battery and its just as bad... why is this happening to me
ill try second to latest radio from xda wiki.. im running out of ideas,what else can i do ?

That really wierd... its not the battery if you have tried using different ones. Its not the ROM if u have changed it.
Have you tried disabling auto-updates? and auto-checks for emails. Which email client do you have? you should find the option to "sync-never" in the app settings.
Buying it from ebay is kinda ominous though.. was it described as faulty? perhaps you could contact the seller and request a refund is all else fails?

you can try using setcpu to underclock the cpu.
i have similar situation as you. before going to bed around 11pm, it showed 50% left, turned on airplane mode, then in the morning around 6am, phone was powered off.
now it has been 2 days, still have 20% left.

Did you ever take into consideration that some part of the hardware might be damaged?
Devices that got water damaged, sometimes show weird symptoms as well:
- They still boot up and seem to work well from the first sight
- The battery drains very quickly
- Some of the peripherals are not working stable or not starting up anymore (e.g. wifi, bt, gps)
- Other crazy things might happen as well (e.g. random reboots, backlight flicker, etc.)
So you might have a look at the mainboard. Red stickers indicate water damage!

Yea but if it were damaged would it show 50% battery after restarting thinking it had reached 5% ? i dont have the tools or will to unscrew it.
i paid 100 pounds fo it, the normal price of a used hero, but the auction said "phone restarts for no reason" and they do not accept returns, so im propably screwed :I

I had an old blackberry 8300 curve, i had it in the bathroom while i was showering, got too moist, turned the detection pads red but phone seemed to work fine after i dried it out. But the battery went to crap progressively in the manner. I would charge to 100%, take it off the charger and maybe an hour it would say less than 10%, do a battery pull and it would go back up to maybe 80% and last maybr another hour and keep doing that till it would normally drain on top od the numerous reboots i would be doing until eventually it would just drain and die.

Can dead pixels cause this ? i have like three.. but then again why would it show 50% after restarting from 5%..
the thing is its not draining the battery, just registering it wrong

Any updates on this? Any resolution?

sorry mate i have tried everything unsuccessfully and returned the phone to the seller.. dont tell me you bought it ? (london)

No, but i have a samsung galaxy tab and experience similar symtoms. It does not bother me too much, the battery life is still great. Just the percentage is off and i need to restart from time to time.
I read similar complaint from droid x forum too.

Battery not charging to 100%

Been running Android for over a week now and this morning when pulling the phone of the charger I noticed it was only at 89%. This is from a full overnight charge.
Got to work and it had dropped to 85% (Watching videos) and plugged it into my laptop at work and it again only charged to 89%
Anyone else had the same issue. Will cut back to Windows to see if it goes further.

Hello dude!
Try removing the battery, wait a few minutes and put it again. See what happen.
Sometimes it is a error when the driver is "reading" the battery settings/status.
Hope it help!!
Same with me, only 90% with all night chage
Same here mine will only charge to 93% while charging overnight
Rebooting into womo and it then proceeded to charge to 100%.
Not a major but a bug that needs investigating.
also had this issue a user responded to me on the builds thread, he said to let it run down to 5% and plug the charger back in. also the one about booting to wm then back on android should fix it.
Same here at 94%. Seems to be a common problem...

Yes, I've got a same problem.
I've heard that no Charging-Stop exists (in kernel), so you may "destroy" your battery because it is overcharging ... so be careful
mine stops at 93%
yeah im a bit scared for my battery...ive been charging it almost twice a day now cause it dies so fast
i even have SetCPU with the profiles from the other thread, but its still draining REALLY fast...
i hope this doesnt have any permanent damage to the battery :S

where did you hear that? can you confirm?
The no stop sounds like complete nonsense. For one, it would be an obvious massive problem so the devs would have worked on it. Two, if you can detect battery charge it would be really easy to make it stop. Three, if it didn't stop, why did it used to halt at 98% for most people?

2)Battery: at current moment extended battery not supported (2350 mAh). Support of them rather complex however.
also battery working in read only mode, it's why during long android usage u can get wrong results. Will be fixed in future.
Hard reset..is only one solution
Actually _everyone_ can get this problem - after reboot u won't able to launch any external exe (exe from rom will work).
It happen because something sometimes can be corrupted during WM shutdown...
I got this problem two times Both time need to hard reset device.
So I recommend to everyone make backups!
So is it confirmed that robot voice (apt voice ) issue fixed now?
^^
confirm problem
read this before post
I have the same problem. HTC wildfire.
Try recalibrating the battery:
1. Turn off all uncessesary apps in the background.
2. Let the battery of the phone run out until it turns its self off.
3. Take out the battery for 2 minutes
4. Put the battery back in and charge the battery until it is fully charged "At least 4 hours"
5. Once it has charged take the battery out for 2 minutes then put it back in and boot the phone up
I managed
The phone was on and charging all night and it was at 97%. I turned off the phone and left it plugged for couple of hours, on and its 100%. Simples

Updated from 2.2 to 2.2.1 now have Battery Issues :(

Hi all,
Basically a few days ago I updated the firmware via Kies from 2.2 to 2.2.1 on my Galaxy S. However, I instantly noticed a huge decrease in battery life - 50% gone overnight when in standby! So I factory reset the phone and had everything disabled - the phone only lost 10% in 24 hours. So I decided to try and eliminate the possible causes so first I turned on wifi and within 2 hours I have lost almost 30% of the battery life with no usage so wifi seems to be the culprit
In the wifi menu network notification is off, however, the device seems to be scanning for networks every 5-10 seconds even when connected! I had no problems like this on 2.2 where I could comfortably get 2 days usage with wifi on. Also as I would prefer wifi to be on constantly when connected I would prefer not to change the wifi sleep policy. Any suggestions would be much appreciated
Many thanks, and sorry if there's similar thread already
which version of 2.2 did you have before?
try a flash back and see what happens.
Or try to drain battery (do not charge till 1% or almost dead) then full charge it.
Always happen to me when I flash my phone to a new ROM.
Thanks for the replies. I've tried leaving the battery till it was almost drained but maybe I'll let it go completely flat and charge it see if that makes a difference?
Also trying juice defender from the market to see if that helps. Not sure if it is a problem with the firmware though been looking around and a few people seem to have had the problem with no real solution
Might have to go back to 2.2 but would prefer not to as I've noticed a big decrease in lag on 2.2.1. Also can't remember what version of 2.2 I had I'll see how the battery life goes over the next few days after trying a couple of drain/charging cycles hopefully won't have to downgrade it. Come on 2.3.2
Thanks for the replies so far
Battery Bug is Major issue with all the versions of 2.2.1, Battery life is very bad. Even the Browser is worst in 2.2.1. May be in 2.3 it will get fixed.
I have tested all the new releases of 2.2.1. I found its smooth and fast.

Very very bad idea to let the battery go completly flat, it's the best way to damage it and even lose 20% of his initial capacity. Never go under 10%.
To calibrate it properly, wait 10% turn off the phone, fully charge it, restart. (do it again 3 times).

The battery is calibrated to do this already, the charging circuit will not allow power to the device unless there is a certain amount of charge in the battery. It's there to protect the battery from this exact eventuality.

That's how it's supposed to be in an ideal world.

[Q] How can I test if battery is bad or phone isn't charging properly?

Does anyone have any suggestions on what I can do to test which one might be bad? Any app you know of that can monitor things and tell me if a rogue app is killing the battery or if the battery is bad?
I was running mik 1.1 and was using it pretty heavily with gaming and downloading stuff. The phone died after about 7 hours. I thought that maybe the rom or cwm or something else might be killing the battery. Something strange though is that, like I said, I ran the battery until the phone shut off. Then I left it off and put it in a wall wart charger for about 8 hours and the status light was still orange. My gf had the phone and told me once she left it plugged in overnight and in the morning it was only at like 50 something percent. I thought maybe the charger went bad so I gave her another one and she didn't say anything else about it. I'm starting to wonder if maybe the phone's battery has a weak or bad cell. I kinda doubt that there's something wrong with the charging circuitry of the phone but there could be, anything is possible. I will probably take it to the repair center and tell them about it and see what they say. I tried looking on htc's site for oem replacement batteries but couldn't find anything. I found lots of aftermarket but I didn't want to go that route.
I don't know if it would not be a good idea or not to try and use my original evo battery just flipped over. I suppose if that's the only thing I have to try and troubleshoot this problem then it will have to do.
Can anyone give me suggestions or has something similar happened to you?
Now let me see if I can find that evo battery..........
Spare parts, in the market if not on your rom by default, had a battery information tab that will indicate battery health as well as what kind of plug the phone detects when charging (usb, ac, or none)
Sent from my PG06100 using XDA App
Like danaff37 said, spare parts can be useful. Also try CPU Spy, free from the market, which shows what % of the time your CPU spends at each frequency, but this actually more relevant for determining if your phone is properly sleeping..
For proper charging you can get an app like CurrentWidget or Battery Monitor Widget which tells your the current consumed during usage or current injected during charging, as well as the voltage in mV. Full charge should reach around 4200 mV, and when charging the current should be around ~800 mA for lower % battery left.
Thanks for your input. I found the evo battery and did the same thing as before. I ran it until the phone shut off and then put it one the (same) charger and went to bed. About seven hours later, it was still orange charging. Both times the phone was off. Now something that could be a possibility is the charger is weak or bad. When I put my evo on it, it charges seemingly fine. I should try using the battery until it shuts off again and use a different charger and see what happens. Six to eight hours charging, with the phone off, coming from a dead battery, on a Motorola charger that has a rated output of eight hundred milliamps at five volts. I have others at different output rates and a two amp charger intended for an ipad. Some might say that the charger is too much for the phone. The charging circuitry only pulls as much amperage from the charger as the phone was designed to. Now on the other hand if I put a smaller output charger on, say one hundred and fifty milliamps, it will take longer to charge the phone than usual. "They" say trickle charging is better. Whatever. I will post my results if I find any. Or, I just might trade the phone in for a nexus s or an evo 3d.
I was just about ready to throw in the towel and say the phone was defective, but then things started happening. I will fill you in on what I have done in the meantime. Okay so the flipped over evo battery kinda works but not completely. It will charge but not to 100% and green light. To test this, I took the evo battery out of the shift. It didn't seem to want to go more than 98 or 99%. I put the battery into the evo and after a few minutes the light went green. This was initially off. Then I booted the evo and let it go to sleep. After it booted the light went orange then green after a few minutes. Okay so the evo battery is capable of going to 100%. These charging tests were done with a different charger.
I forgot to tell you, I let the evo battery charge while I was at work and the phone was off. So the battery was charging roughly twenty hours and still no green light. I suspect that even though the positive and negative terminals aligned with the correct tabs on the shift, the center two contacts must be different internally than the shift battery. I speculate that those center tabs are for the battery and phone to communicate to each other during it's charging state. I am guessing that the battery tells the phone it is fully charged and to go trickle charge and perhaps the evo battery wasn't communicating to the phone or the phone didn't know when to say it is done charging. The battery never got hot either.
The shift was rooted, running mikshift 1.1 and the latest clockworkmod recovery. Here is where I suspect that there still might be charging bugs with that setup. I used the pcxx.zip file that when booting into the bootloader, would flash the phone back to stock everything. After trying this and assuming that the phone was back to stock, I kept going with my what the hell is going on with this phone battery charging test. A note about the flipped evo battery. Yes it will work in a pinch but it won't charge properly. Luck has it that the notches in the battery and phone allow it to work in a shift. Only thing is, the shift battery won't work in the evo. The tabs are on the wrong side and the phone's tabs won't allow the contacts on the battery to meet up with the phone's terminals.
Okay, where was I? Trying different chargers wouldn't make the shift green light full charge. I tried the same chargers on the evo with it's original battery in and it would green light after a few minutes on or off. There wasn't anything wrong with the chargers. Oh and another note, while using the battery monitor widget, I noticed that both phones wouldn't pull more than a little over three hundred milliamps of power from the charger to the battery. Interesting to know how much it really pulls from the charger.
Anywho, I tried something different for my process of elimination testing. I actually ruu flashed the shift back to factory and guess what happened..... The battery and phone were charging both on and off all the way to green full charge at 100%! I think I'm getting somewhere with this! All my luck, either it is a known bug somewhere in the forum in a place I haven't stumbled across or I'm the only one that this is happening to. It doesn't really matter I guess.
My conclusion, which isn't scientific by any stretch of the imagination, is that the phone isn't truely back to factory unless you ruu it. The pcxximg.zip doesn't put everything back to stock. I haven't narrowed it down to what is causing this behavior. I don't think it is root. It could be cwm recovery or the rom or both. I didn't try the stock rooted zip either. I suppose I could go further with this investigation but I am too lazy to now. I might root it again and just leave things stock rooted. I might activate this phone in the morning and run it all day tomorrow and see how it acts. I will have to charge it a few times during the day to keep the levels up when I really use the phone heavily. I've written enough for now. Does anyone have anything to ask or add to this topic?
Since the latest update to CWM phone-off charging finally works again but the light never turns green. It charges fully but with the phone off the LED never turns green. It's not just you.
EDIT: If this is not the actual question I apologize. The posts were far too long to actually read
^ Shift Faced
OK. I thought something might have been broken.
Forgive me, I am truly a newbie to Android after having a BB for 8 years. This battery thing is killing me. I am on my 2nd Evo Shift, the 1st one wouldn't last for more than 2 hours with barely any usage so they gave me a new one. This one barely lasts 5 hours. I am barely running anything. I took it into the store and they thought I was going to be running all these programs, but I kill everything. They told me the "battery trick" about turning off the phone and unplugging it and plugging it back in 10 times so I did that but I am not getting any more life out of the battery. My display is constantly using at least 70% of the battery it says even if I turn it down very low or if I set it to choose its setting. Do you have any advice for me? I am not running a task killer, I kill all the programs I am not using. I have no widgets running because I am afraid to use the battery, I only have 2 screens out of the 7 with things on them. I am being help hostage by my cool phone that I want to use but am scared to kill the battery! (sorry for the long post)
Ok if you use a lot apps just close them after (for stock 2.2) . Even on stock you can literally stream music and movies for about 4-6 hours. (sometimes a lot more) . The background info that runs doesn't use a lot of juice , but if you want you can go to your home screen any of them hit menu (but not with the app drawer open) select settings go to accounts and sync turn off background info and just turn it on manually when needed such as the android market . You can also turn off the auto sync and just manually choose to sync , like in the clock (and gmail etc.) it will say no weather after you click it , just hit menu you will see a little sync button option to sync and voila you have weather . So when you visit the market it will automatically ask you to turn it on (background info as will all apps that need this) . And the screen on any android is a battery killer . So when not using your phone simply tapp your power button to turn your screen off and lock (and to keep from pocket dialing lol) . But if all you do is text , emails , and web surfing (surfing drains more but no where near as much as streaming) you can literally do that all day , the screen will actually suck the most power . If manually turning off your apps is too much . Just turn your phone off (not just the screen) and on . If a new app didn't turn off after you start your phone back up you know that will be a problem later . So when not using your phone turn off your screen it will last soooo much longer . I only make a call or two and a couple of texts maybe a few minutes of internet with opera mini . My battery lasts over 24 hrs , but I barely use my phone . Hope that helps .

BTW if you have a bunch of apps running in the background video games etc ... and you charge your phone all night and in the morning it is not charged . You should probably turn your apps off . Or simply power your phone off which shuts off most apps . Then turn it back on . The phone should not take all night to charge , it should only take an hour or 2 . 3 hours max .

i suggest watchdog lite,it monitors cpu usage and alerts you when 1 uses more than your max threshold.if this helps,please click thanks.
When you changed ROMs, did you do it with a full charge? If not, your battery stats file is probably messed up.. Ive used Battery Calibrator free from the market in the past to fix that problem.. I believe a brand new battery on the Shift shows about 4200mV when fully charged or just slightly below that.. Run the app, when it gets close, calibrate (which essentially just deletes the battery stats file and creates a new one)

Battery reading issues

Hey everyone. So I bought a second hand note 4 recently and have been having battery problems.
I did a full wipe install of CM13 and the battery dropped to 0% at random times and I had to plug it in the charger for the phone to even boot as it would just restart as soon as it turned on. Anyway, i thought this is probably due to faulty battery. I purchased another one and now this one doesn't reboot at random times but seems like the phone keeps reading the battery percentage wrong, sometimes it doesn't charge over certain percent, just gets stuck at 77% or 63% or any percentage really. If I remove the battery and plug it back in, it shows a completely different percentage everytime. I have tried wiping battery stats, do a full discharge/charge, nothing seems to help. Battery drains fairly fast too, once I manage to get it to 100% it shows that expected time is like 2-3hrs if screen on. Thanks!

battery displaying different percentage after u remove it and put it back in is normal i have 3 note4s all do the same (up to 10 percentage change, it either increases or decreases) but the other issues like getting stuck on a certain percentage are not normal make sure u have the genuine battery and try stock rom.
yeah, i tried stock and the same thing really. such a random issue. I just noticed that battery charges once I turn the screen on and use it , so it only gets stuck on random percent only with screen off.

yeah, i said I wiped battery stats, which is basically recalibration
once the battery is charged to 100% it also drops first 10-20% really fast and then it gets better but still I only get around 2hrs screen time

the only way to fix this replace your battery by new one
i tried all options (Format ROM - Wipe battery status - Getting back to stock ROM - Unroot - re Celebrate apps - Changing recovery-Removing battery from device for while sleeping - charge without fast charge - charge via USB)
i asked myself after that all of this headache doesn't worth 20$, i replaced the battery with new one and its working fine now

yeah, i replaced battery as well but it's still the same issue. old one at least charged fully but would randomly reboot on me, the new one doesn't reboot but drains extra fast and doesn't always charge fully. can't believe both batteries are faulty
I am sorry for summoning this old post but did you find any solution to your problem? I have exactly the same experience with my note 4.
Thanks!
Is there a solution for this problem?
Power down and then out-and-in same battery and my stuck-at78%... was 100% when started.
if you having problems with auto restarting.... download the app " WAKE LOCK" and put it on Partial Wake Lock setting... your restarts will be a thing of the past.

Random turn off

Hi,
I have a Note 4 SM-N910C variant that is almost 3 years old.
Starting from 5 months ago the battery level would start dropping fast from 35% to 0% in like 2-3min after which the phone would turn off. If i took out the battery and insert it again, start the phone again it would show around 30% battery level. After a while it would start doing the same fast drops in battery level and so on.
I got a new battery, not OEM and now it doesnst do what i was facing above but it randomly turns off no matter if im doing something with heavy or no load on the device.
The turning off usually happens after the device goes bellow 50% battery level.
How can i test if all the components are ok other than the battery which seems to be faulty in my opinion.
I did order a new original OEM battery but it will take time to get to me.
I want to find out if the rest of the components are functioning without faults so i can decide whether i should get a new phone or not.
Please assist.
New battery
I know its not the same behavior, I have 2 note's. Mine is only a couple of months old while the one from my wife is build in 05/15. Her phone when we just received it would refuse to charge above 96%. Sure the phone would say 100% but as soon as you unplugged the charger it would drop straight to 96%. It did this on 3 different batteries, exactly the same behavior. All these batteries are OEM. When you plug it in it would go rapidly to 100%..
Anyway, I wiped the cache on that phone and since this it charges normally.
Been comparing the battery drain and both phones are using around 6 to 8% per night while on stby with wifi on.
Just try this, it may help you!
Thanks for the replies.
I did try wiping the cache and even did a factory reset.
I rooted the phone 2 days ago to try and recalibrate the battery but i didn't help.
I think the situation isn't degrading cause from today the phone is constantly hot and the cpu is running at around 48 celsius with 7-8% load.
I'll see what happens when the new battery arrives, maybe the phone is heating up cause of this maybe not. It's even eating the battery from 100% to 0 in 2h with no real load on the phone.
Do you guys think a benchmark program will force it to thermal shutdown if this is the issue.
I'm still trying to find out if only the battery is faulty or i have a dying phone.
To me you have 2 problems...a faulty battery and a (new) software problem on your phone.
Constant being warm with a cpu load tells me something on your phone is running all the time consuming your battery and causing your phone to heat up, unless it behaved the same before the factory reset and rooting?
You are rooted so try Wakelock detector for root to see which app (if any) is causing your phone to behave like this.
I will try wakelock to do its thing during the time i sleep. But if that doesnt help ill try a custom rom. Im not gonna factory restore and go back to stock rom. Gonna move away from that and see what happens.
