Battery problem

I'hv flashed cm7 last week. The problem is that my defy battery drains too fast as compared to stock Froyo. I have calibrated its battery correctly. Also phone always remains hot. I am looking for solution but didn't get proper solution. Plz help..

I've noticed the same, since flashing CM 7.1 my battery will barely last the day, I don't think it's going into deep sleep.

I'm having the same problem

When I flashed CM7 the second time recalibrated and deleted battery stat battery life improved...now i get about 35-40 hrs on one charge.
But of course there are many factors that contribute to battery life and our devices won't be the same.

Not proper solution yet..

I had problems too but after the Calibration the battery works just fine.. try Calibration again

Thanks to all..will post after getting my problem solved.trying cm7 stable..

I tried cm7 stable..here battery is draining more quickly..is there any ROM for better battery performance..?

can you give us some numbers and specifics about your usage ? its not possible to give any view point or explanation till we know whether you are running on 2g or 3g wifi on/off etc etc .

that your phone remains hot can be caused by two things (in my experience): your cpu is always on 100%, or your gps is on. First of all, try wiping battery stats from recovery when fully charged, than let it discharge. secondly, try using setvsel to control the frequencies. if your battery still drains fast, check whether its water damage indicator is red (the - originally - white sticker near the battery pins), cuz mine is red, which means it was contacted by water, which couldve caused a short, and till then my battery drains much faster.

You can use cpu spy from market to see what is your cpu doing and the times for each state. Check if it's going to deep sleep.

I always keep my GPS, wifi off.
CPU is undervolted at minimum values as 300-16,600-26,1000-46.
I've already calibrated battery.
My battery statistics are: (approx.)
Display- 40%
Android system- 10%
Phone idle -15%
Cell standby- 10%
Android OS -5%
Remaining- other apps
Display is taking 40% while I always keep it at minimum brightness.

I finally got solution.. My defy's battery performance improved a lot. I have installed wakjiui ROM and calibrated the battery and it was unbelievable. Using it since last week. Almost doubled battery performance. At night it drains by only 2%. And one more thing about wakj ROM is it is perfect combination of miui and some apps from cm7. .

i got 48 hours.. sometimes more using MIUI .. highly recommend you to use it!

It is based on miui.

[Q] My HTC One V drains battery fast and lag

HELP EVERYONE
MY HTC ONE V drains faster even in normal use.
I just use the phone for texting
Wifi OFF
Data OFF
GPS and Location OFF
Bluetooth OFF
from 77% after five hours it became 39%
and also is the HTC One V lag? is it normal? how to run the device so smooth?
THANK YOU IN ADVANCE EVERYONE FOR HELPING ME. GRATEFUL :")

Def not normal. My battery with everything on WiFi, sync etc. And playing music for 4 hours my battery is at 72 after 10 hours

You have an app that uses the cpu too much = it eats a lot of battery.

Yea true! Some app is sucking the juice off your battery! See if you have some background app running which is trying to connect to the Internet (Since you have both data n WIfi off). Usually these apps eats up a lot of CPU speed. Could explain the lag issue too
Also does you phone heat up?

Great battery life on this phone. Better than most I've tried. Watch what apps you have installed as well. They might be tapping the juice in the background.

yep something is draining ur battery and eating lot of ram
wt free ram ua having?
and if u use swift key x thn think twice it uses more thn 3mb ram when u nt using 50+ whn ua using
soo think ovr it
dnt keep screen brightness to max
it will drain juice twice faster whn ua at home keep it low and when out 25% is enough to make u see the screen in bright daylight

Yes I must point out that the battery life on this phone as I have observed is quite above average.

I definitely agree on that. At this day and age of smartphones and their battery lives, this phone is rather exceptional.

Use apps like Watchdog and Wheres is my droid power to check what is using more cpu/battery! And remove it or find a alternative

Its always better to install apps which are without ads (mostly freewares are like that only). Keep the brightness at optimum coz its the screen which uses most of the battery.
The more the softwares are running at a moment, the more the RAM is used and hence the battery runs out qiuckly.
Dont keep wi-fi or internet connectivity open always.
Or else u can install third party softwares like Juicedefender or Easy Battery Saver.

Oh and most importantly NO TASK KILLERS!

Or you can install the program AdFree, set the adress ip for ads to be ignored and you will have your phone ad free .
And those softwares "juicedefenders" are good on a short term but on the long run it causes problems.
Use it as stock without any programs that help you to have more battery or **** like this..

Check the battery usage through Settings > Power > Battery use.
No need to use a third party app for this (unless you've removed this by any means).
Sometimes software issues cause these problems on the phone (even on the stock ROM). Common culprits are "Phone is idle", "Inactive" and "Android system". If these are reporting battery use above ~10% (and you haven't actually had the phone inactive for most of the time), the problem should be resolved with a factory reset.
Otherwise, unless you've tampered with the bootloader this would be covered under the 24 month manufacturer's warranty (12 outside EU) and the device should be sent in for a battery swap / given back to retailer as DOA.
Also, the device isn't the fastest one. The processor is running at 1Ghz with 512Mb of RAM to go along with it. The solution is to load a kernel with overclocking capabilities (Titanium for example) and crank up the CPU to 1,5 or 1,7 GHz. I would assume all of them can run 1,5 GHz as I suspect the processors are actually underclocked to keep battery life long.
Obviously this would reduce your battery life, but having less than 24 hours of battery life on an unmodified One V is what I would call poor unless you are a heavy user.
I hope this helps.

Actually, a good kernel can improve battery life even if you overclock your cpu. HTC's kernel doesn't come with all the tweaks available for volting and battery life. So if a good dev makes a good kernel, the battery should be the same as running on stock, but with faster performances. Adi_Pat has done a great job with his kernel. I was running it for 2 days until I needed to get a replacement for my phone and now I am waiting to get a new one so I can run it again. I even overclock it at 1.9 ghz and run it for 1 full day and after almost 8h of wifi on, the battery still had 50%. So if you don't have an app that kills your juice, you have definitely a poor battery built in.

does it lag
it was going to buy this phone but saw this vid /watch?v=JptIYZl8qmE that said it was very lag. do you think i should buy this or the sony arc s. plz help

I had some similar issues until I did the following:
Run the battery completely dead until the phone shuts itself off, then put it on the charger with the phone off. Charge it until it is at 100%. Take it off the charger and turn it on. Turn it off again, put it back on the charger until the LED is green, then turn it on again. This helps Android to calibrate the battery.
Install Quick System Info and see what apps are running and how much resources they are using. Also, close all apps, then go into Settings>Apps>Running and see what is running. Look for any apps that shouldn't be running and uninstall them. You have something running in the background and need to get rid of it, this will help you do that.
Uninstall Swiftkey X or Thumbs Keyboard or any other keyboard apps you put on there. Uninstall any weather/clock widgets like HD Widgets or Animated Weather. Use the stock keyboard and stock weather widget (they both work pretty well).
After doing all of this I consistently get home after 10 hours from work with about 60% after moderate usage. I also have almost no lag unless I am playing a more graphically intensive game. Couldn't be happier.

Battery use playing heavy games

Hi you lucky S3 owners. Could someone please tell me what the average use per hour is playing a game like:
Modern Combat 3
NOVA 3
Shadowgun
Please some info.
Thanks for taking your time.

Seems like no one plays games??

Brilliant
Since being a heavy S2 user i was never to impressed with its battery life (May have been caused by running a custom rom?) but i have a noticed a hugely significant improvement since using my S3 and it seems to handle games like a charm, Runs them extremely smooth and doesn't seem to drain the battery at all, I play NOVA:3 for hours on end and it only seems to take about 15% battery for an hour and half of playing, which I think is pretty good

Battery is brilliant on heavy games and multi tasking.after 3-5 cycles on charge, the battery and quad core really makes the phone fly with minimum drain.
@klinkso
Remember to calibrate the battery, after flashing.this can improve battery drastically on heavy drain

Hi, now that i have your attention!
I have cm7.2 democracy on my gio
I barely use it for wifi or gaming now because the battery is S**t.
I had 2.3.6 GB before and battery could take out 2 days on games and music. Now suddenly after switching to cm7.2 i need to charge it twice a day without using any app or game. just some texting like 10, 12.
I use ondemand governor and max freq is 806 min is 245
Also a couple of times i have seen that when my battery is at 30% and charge it then within 5-10 minutes it showed 100% charged. Unplug the charger.
Any suggestions or something on this? I really need an answer guys. Thanks

I can tell you that you can't charge your battery within 10 minutes.
Charge it at least 2 hours, 2.5.

Yeah! I will. Even if it says fully charged. IDK whats the problem with it. It drains so quickly.
Even if i charge it 2 hours even then i have to charge it twice a day.

I have the same problems. Some help?

I am having the same happening with my phone. I am looking into buying a new battery.

My phone goes from 100% to 10% on five min plz help

No one has found a solution 'till now?I'll try to use ODIN and go back to stock version, maybe that will help. Has anyone had those battery problems before using a custom ROM?with stock my battery used to last 2 days with games and music etc, now I can only use it for 5 hours without any games or music or internet. It also charges from 0 to 100% in 30 minutes , maybe less. I'm still hoping someone found a solution for this problem because it is useless to have a phone without any battery.

Try to get a new battery because huge draining problem is not caused by roms it caused by battery damage.my battery runs on stock rom over the 10days without using anything but on cm9/10 roms it drains faster but still runs more than 3days for me.

so no one got it?
Thank God I am not the only one here
But guys, I have been using stock GB for an year. Its been only a week on cm7.2 democracy and nightly.
Both have same battery issues and non of this happened in stock
It's not the battery issue.its something else. I'm sure

Have you tried going back to stock version using ODIN?I think that is the ultimate solution before sending my phone to service(I still have warranty).

Try to "recalibrate" your battery; in cwm theres an option "wipe battery stats". some say its nonsense, some say it really helps; i would give it a try.
No idea if theres an option with stock roms, though.....

I'm calibrating now...Will post the result in a while. (Tomorrow i guess)

I still couldn't solve this..I flashed the stock firmware with ODIN and still no luck, I'm starting to think it is a hardware problem, maybe I will send the phone to service now that I have the stock firmware back. Has anyone found any solution?

Hey, i found this article
For the users who like to try out new ROMs very often or by default Android receives updates to Android very often. These updates re constantly pushed to the users to provide the better experience to the users. For those who flash their mobile handset with custom ROM they are advised to charge their handset to 100 % battery life and then proceed with the upgrade processor. That is advised because if you have 50 % of battery life and proceed with firmware update, the new custom ROM will consider 50 % battery life as the full battery stats and this will provide half the battery life then earlier as specified by your phone manufacturer. In those cases you need to go with the battery calibration to gain 100 % battery backup as specified by your provider. There is complete procedure on how you will calibrate your phone battery is mentioned by us and if you would like to make the process very much easier then you can make use of a specially designed application which calibrates your battery. (Battery Calibration)
Okay so i flashed a new custom rom with 100% battery but no luck on battery issue. Its still draining the same.
then i calibrated my battery with this app with my battery at 100% which of course is 50% as said by this article, the app said "Your battery has been calibrated by 6%". Don't know what that means.
ANY HELP? DEVELOPERS PLEASE GUYS!

Try to calibrate it too.It may fix it.

I have the same issue, I am using CM10.1 RC0 by Olddroid but I think my problem is the charger. For the last month I charged my Gio using the usb connection from PC. Now, if I use the charger the battery drains faster than charging with the usb connection method. I am gonna buy a 1500 mAh battery and hope to solve this problem.

[Q] Battery charge increasing CM9

I have a strange problem with CM9 . I noticed that when i use the phone until the battery is too low , less than 10% , then leave it with no use for a while the battery percentage increase .For example it was 2% and suddenly it became 5% with no charging .
P.S : Just flashed CM9 with no changes, mods ,or tweaks.
Thanks

hi,
i had that problem too, it was just the battery being on the way to it's death. first, there was the thing you described, then, after a while, i noticed that the battery bloated up a little. i continued using it until it eventually didnt fit in the case anymore and bought a new one then. i was using cm9 b3 at that time and i still am, since it's not a cm9 issue, just bad quality of the battery. so, consider buying a new battery soon

Hahahaha, it's very common, I'll try to explain it to you: If you are using your smartphone quite hard (games, internet...) it starts to calculate how much time rimains using battery (specially when it's under 15%), and it changes the percentage, but when you stop using it, the mobile phone recalculates again how much time it remains and change again the percentage, but it improves because you are no longer using it so the battery will work for more time.
Sorry for my bad english, I hope you will understand.

Thanks guys , so is it the battery dying or just the phone calculating how much my battery will last ?
