i've read about similar topics, but i think i did not found answers...
i've been aware that x2's battery drains fast. i had lots of bad experience with this problem so i decided to buy a new spare battery. to describe my problem, here is the scenario.
1. i fully charge my new battery
2. i remove my new battery to charge my old battery
3. after my old battery is full, i remove it to use my new battery (which was fully charged 4 hours ago)
4. after turning on the phone, it reports (immediately) BATTERY IS LOW.
5. i scratch my head why, replace it with the old battery instead, turn it on, and reports LOW BATTERY also.
i think this is a phone problem and not a battery problem. what do you think? why do i also encounter same problem with my brand new battery?
please help. thank you...
this is a new problem i encountered after reformatting my phone...
did u try flash to another firmware?
I had similiar problem as u when was using firmware Genenic_sg, flashed to Generic_en then its gone
by trial and error...
by trial and error, i found the solution... (once my main battery runs out of life, i do this steps...)
i let my spare battery stay on the phone for about 10 seconds before turning it on... (something like at least, the phone will recognize the life of the newly inserted battery)...
there are occasional times however, when the battery meter will still say low battery life even if i already had the battery stay before turning it on... so what i do is just turn it off again, remove the battery for few seconds, reinsert it immediatelt, and turn my phone again... and voila! it's finally recognized as 100%.
Hello,
I can't believe this has not been mentioned already - but I've done a search and I can't see anything regarding this subject.
I'm just curious as to the battery chart in regards the Display. It is always really high. As a test - I charged my phone to 100% and then over night left my phone alone, with the screen off to see what the stats were. When i awoke the battery chart had the display eating up 54% (even though the screen had been off all night).
Is that normal? Can the Battery useage chart be trusted?
I'm running a rooted device - with XE2.
Am I missing something here
My chart has been 100 precise for me. Post a screen shot if you can.
Also make sure you are not running NoLED.
Yep, ill sort a screen shot out.
And what is NoLED?

So you are NOT running it
It is a utility that uses your screen to display notifications, because there is no LED indicator on the phone that flashes for missed calls, voicemails, messages, etc.
NoLED displayes those little dots on the black screen itself.
Theoretically it makes the screen to be always on, and wastes extra power. But again there is a huge market for that great app (developed by an XDA member here).
Ok - here is a screen shot. Anyone else getting results like this even when the screen is off??
I got the same battery issue like you when i was on KE1.

i have the same problem, my sgs2 is so bad whit the battery life, i cant use the phone a normally working day from 07:00 until 17:00.. and allways i see the screen in the battery chart all the time whit more then 50% battery usage.
if this problem still exist, i will sold my device, thats not for a daily use..
Same answer as always .
Your display has been the part of the phone that has used most of the power used .
NOT your display is using 70% of the battery .

but did you read the first post from the theard owner? over the night, the display stay the whole night off, and use more then 50% battery.. thats not normal sorry.. a device which runs between 4 and 6 houers its a device for fun and play, but not more..
when im driving to the work i need 1 hour and 20min.. in this time, the screen is maybe 10min on while im listening music, and in this 1 hour and 20min my battery drain is 22%..
unbelivable...
from 07:00h in the morning until 12:00h 5 hours later, my battery is on 50%. i had htc desire hd before, and this device had a 1300mah battery and it was better than samsung whit 1600mah..
im really dissapointed..
The display = the majority use of the battery fact .
OP thinks display showed using 54% of the battery overnight .
It showed as a percentage of the total power consumed that the display consumed 54% so if the battery dropped 10% of its capacity overnight then 54% of that was from turning the screen on .
I repeat the battery usage shows what has been using the battery as a percentage of the amount used it does not show the battery drain ,Or even amount of battery used in that time frame
||||||||||Drained 50% of battery today display 20% .
Drained 30 of battery yesterday display 70% ..
WHY HOW AND other stuff regarding battery usage on SGS 1 forum .
jje
after the night was the battery down 54%, e.g. have you lost %46 battery over night? Or was battery down to lets say 90% but display accounted 54% of that 10% loss???
Battery 100% to 99% that is 1% used thats clean with no battery stats .
Battery stats usage shows Display 74% .
Or the display has used 74% of the 1% used .
Its a really simple reading of the usage of the battery by the varying components its not a measure of the battery .

thats what alot of people dont understand it seems........
i think we didnt understand us..
i try it again.
we start whit 100% full battery.. you dont touch your phone over the night.. and when you stand up, you look on it and see, the battery(only a example) is on 50%.. from this 50% which battery loose, 50% goes to the display.. so, the real drain from the display is 25%, over night, and you didnt switch it on.. you think that's not too much?

yes its a problem. when i do that same test on another phone, display does not appear in the list. if i charge to full at night, unplug and go to bed. when i wake up 8 hours later, the top of my list says Cell Standby, WiFi, Android OS. Display does not appear.
once i use the phone for a few minutes, display jumps to the top very quickly.

i want to share this whit you, at the moment it looks like my problem is gone.. i will take a look on it today, but right now i look on it, and after 6h over night whitout ac and any use, the display is not listed and my battery drain is in 6h 8%.
what i did:
- boot in recovery mode
- wipe data
- wipe cache
- power off
- boot in download mode
- download follow rom:
http://galaxy.androidgamer.org/Firmware/GT-I9100_XWKE7_XXKE4_OXXKE2.zip
(rom is splited in three files, pda modem and csc, csc is oxxke2 is newer than
the original one in the xwke7)
- in odin choose repartition, auto reboot and force time, i allways flash whit the
pit file, so download it to if you want
---> finish.. other steps like root is not neccesssary to describe here.
---> i will report again today in the evening.
for me its better right now.. i found the drain is to quickly again, but really much better.. something around 22h, but whitout a lot of use.. this time on the first place is the android os in the battery chart.. display is showed on the place 3..
I've been having a problem with my battery for a while now where the mV's stay where they should and the percentage drops really fast leaving me with horrible battery life. I've tried calibrating my battery plenty of times and tried various guides and fixes but nothing seems to fix my battery. Can anyone help me or should I invest in a new battery? Thanks
For example, I took a screenshot while my battery was at 3593mV (4200mV is full) and it said it was at 15%. This happens on every rom I flash but I'm currently on Miui Alpha 3 if that makes any difference.
i am sure you have looked at this thread... http://forum.xda-developers.com/showthread.php?t=1407569, it seems there are a few of us that have some battery issues.
I have seen that thread, but I'm not sure if I have the same problem or not. For me, the percentage of my battery just goes down way faster than the actually charge on my phone.
for some reason, i think that its the way the phones are reading the data. the math is wrong. the only reason why i am thinking this is cause my dads phone is doing the same thing, not showing 100% charge when it should be.
what happens when your phone reaches 0%? does it shut off? whats the battery voltage when this happens?
My phone shut off at 0%. After rereading that thread I managed to fix my battery by doing this:
1. Charge to %100
2. Use a wall charger and take the battery out so it shows a question mark, then put the battery back in till you think its at 4200mV
3. Keep phone plugged in and delete the battery stats in /data/system, and cc_data, cc_data_old, and powerup from /data/battd
Hope those directions are good enough, hope you get your batteries fixed!

post back and let us know if this is a TEMP fix. it was in my case, but i did not remove my batt stats.
Heyy, so i figured out how to get a better battery life off of your htc one device! If you go under settings>apps>all, and disable the ones you DONT use as much or at ALL it will help out a whole lot. I also only use the power saver option, i keep sleep mode turned off...
I have also posted a picture of what my battery usually is from day to day...
Would love to find out what everyone else does to save battery!
