[Q] A Diff Kind Of Issue With My Battery

Did some searches and couldn't find anything like it. The only thing I can think of is Data is corrupt somehow. Anyhow, my issue...
Did a reset a couple days ago and in the reboot system kept giving me an error, then it would retry the boot. After about 5min of that i pressed the back button and it bugged out. Sorry, little white letters move so fast it's hard to ready what it said. Anyway, from that point it booted just fine.
Since then I have noticed an amazing increase in my battery life. Data and Sync on, I'm getting 1-7ma in standby. With GPS on I get 11-15ma in standby. I have now gone 3 days with moderate use and have had my phone on the charger for less than 2 hours. (USB CHARGE and not including just now)
Now, your prob asking how this is a problem. My problem is, I am getting those same numbers when I CHARGE my phone. As of now my phone took 3.5 hours to go from 67% to 85%. My power widget says it's getting 11ma+.
Essentially I got awesome battery life but craptastic charging speed now
Does anyone know of a command prompt thing I can use to wipe my battery data? I have a feeling it's throwing things off...

[Q] [Help] My battery is draining too fast, some soft problem ?

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.
Sent from my HTC Desire using XDA App

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.

[Q] Consistent reboot problem with tattoo

Hello there everyone!
So, first if of all allow me to say I'm a programmer/network administrator so I know things around *nix systems and Java, and right now I'm having a quite boring problem with my Tattoo.
Here's the history:
Got a Tattoo one year ago, v1.6, all going well, suddenly it started rebooting, some months ago, dropping calls and would sometimes loose network. In the meanwhile I used another phone and left the Tattoo alone.
Now I decided to pick it up again and sort things out.
Problems:
Phone sometimes reboots randomly
Phone reboots specially during phone calls
If I select the use 2G Networks Only, the phone restarts some seconds later
What I have tried:
- Changing SIM card
- Flashed latest version from: http://forum.xda-developers.com/showthread.php?t=939122
- Full wipe as well
- Formatted SD
- Factory Reset
- Cleared Dalvik Cache
Clearing Dalvik Cache allowed me to keep a phone call for more than 30 minutes though.
The weirdest situation is that *every* time I select the Use 2G Only option the phone reboost, some 5 seconds later. Every time.
Any suggestions? Completely lost here.

Shameless bump...

Late, but, I had have same problem when the battery is not calibrated.
I seems to happen when the Tattoo appears to have enough battery, but it not true.
Charging (up to 75%) and calibrating battery works for me.

It's never too late
Can you elaborate? I still have it so I'm willing to give it a go in the next hours and post results...

Charge your battery to 100%, go to your recovery, advanced, wipe battery stats. Then discharge fully and charge 100% again

Great, thanks!!

[Q] Nexus 4 Instant Battery Drain/Shut-Off

Hi
I have recently started having a problem with what I presume to be the battery of my Nexus 4. It seems to have started suddenly about a week ago, though was working absolutely fine before. I don't think it was due to any specific app having been installed. I have also done a factory reset on it, but that didn't solve the problem.
Basically, the battery will discharge to about 75%. The phone will then suddenly switch off; turning the phone back on, it simply shows the battery to be fully depleted and switches off. If I plug it into a power source, the phone turns back on and begins charging, from 0%, though seems to suddenly fully charge it within about half an hour.
My phone has not been rooted.
I would really appreciate any help/advice on this issue as it is incredibly frustrating having to have my phone almost permanently on charge.
I have attached two screenshots of the battery usage graph.
Thanks!

If you are on stock, try flashing the stock image(4.2 or 4.3 up to you) there's plenty of threads on here thatll guide you thro the process.

I've had the same issue about three times, during the first week of using my Nexus 4 (about half a year ago). I've already had my mind made up to RMA it, but waited for it's shut-off to happen once more to collect some evidence of this problem and... it never happened again. I'm pretty confident that I didn't install anything that might have helped (I only installed BetterBatteryStats to check the instant drain, but really doubt it could change anything, it's just statistics), and I've never factory wiped the phone's data yet.
I've been searching for answers around the internet back in May, but never found anything of value, so my only advice is... wait a little, and if it doesn't get better itself return it to the merchant. My previous HTC phone was restarting almost everyday from the first day I bought it, until a month later I returned it for warranty repairs and after they changed almost all internals of the phone it never crashed again (till today, since I still use it as GPS and media player when running).

Mi 9t drains battery under night

Hello, is this happened to everyone else? It just drained down to zero in just one night, any fix?

is This happened to you after charging your phone? This happened to me once, I was charging my phone and after reach 100% I unplugged this was on the night, 6 hours later in the morning I noticed battery was 4% this means 96% was eaten on that 6 hours. I was on a rush, so rebooted the phone and plugged to the charger again. Like I said this happened once. I'm not sure if some app/google service/service keep my phone woken all that 6 hours.

It happened to me also. Same as above comment

Same for me too, but my phone was fully drained.. Maybe a software update will fix it.

Happened to me before debloating my phone and while keeping the phone under a pillow.
Maybe a clash with the feature for detecting if you're using the phone to show the fingerprint icon on screen? I disabled that too now.

Happened to ne yesterday. Weird. Eea stable 10.3.12

it's pretty crazy. it happened to me 2 times. battery drains is insane, about 15mins I lost 8 to 15 percent!!!
first time I did everything I could to stop it but no luck, I decided to do a factory reset and it was fine for two weeks. the second time started yesterday, I even tried gsam battery and enabled the more stats using adb. all it could find were consuming the battery are :
1- kernel android os
2- system adsprpcd
I've tried these still no luck.
1- clear data :
play store
play services
google
2- disable dual sim 4g - note: I use one sim.
3- disabled all the apps in permissions>start in background
4- uninstalled about every apps I've installed

In my case I struggling with Google Play Services eating up my battery, I tried everything (xiaomi.eu rom, full restore, clear cache of Play Services etc...)
The issue it's still present even with updating the app with the newest versions. You could check you consumption to see what's using your battery

Not very healthy habit btw, better not to have the phone so close to your head all the time as battery consumption could be later your least problem.
Did your steps helped in that situation? As if pillow would be the culprit, some of the flip covers could cause the same.

I didn't have the issue since, but I don't recall leaving it under a pillow since either.
My entire phone setup is documented here so you can try uninstalling the crap I've uninstalled and the relevant settings for the FP scanner.
