Upgrade from Eclair to Serendipity(Froyo) Battery Doesn't Last

I've viewed many posts on battery life on xda but I still don't know why my battery doesn't last even when I am not using it.
I disabled wifi/gps location, disabled facebook/twitter widgets and any other logical power usage. After that I powered it up to 100% and after two hours with no usage the battery dropped 15%. I installed an app which will let me know in a day or so which apps are sucking the life out of my battery.
Do you have any ideas?
Thanks

Recalibrate the battery.. lots of info on xda. Mine went two days the last charge...

You might have flashed it when your battery wasn't full?
try recalibrating the battery?

That doesn't always help. I had the same issue with Serendipity. It is a good ROM but for me it just killed my battery. It was mostly draining during sleep periods which it should not. I have had issues with OC/UV kernels and I just decided to switch ROM's rather than try another kernel. Nothing wrong with the ROM for me other than battery drain, which is an issue between phones from what I have seen.

try firefly + speedmod kernal
give it a few days to settle in after 2-3 days use my battery life had improved tremendously

Since flashing to Serendipity my battery life has just about doubled from ~6 hours to more than 12 hours of heavy use.
I use WiFi, GPS and Bluetooth continuously with very little3G data or voice communications.
I never use the media player or the camera.

Try the Di11igaf's 5.1 rom. The battery is amazing for me. Just flash the rom at 100% and then recalibrate and set clock at 100mhz and uv at 50 75 75 100 125 125 (1280 to 100mhz)

Serendipity isnt the problem ...

Agreed. I believe it's user error.

The culprit was wifi, as it would randomly connect to a network and some apps started to sync. I"ll try to recalibrate the battery and disable wifi for a day and see how my battery lasts.
Thanks for all the help

Need better Battery life!!! help!!

hey im using leedroid v1.3 and the battery life on my phone is horrendous, i left the house at 11am this morning with 98 percent and after a 10 minute phone call i had 75 percent battery by 12 oclock. do you guys have any tips or things i can flash to get the phone through a day and a half or even 2 days somehow?
also having an issue with the speakerphone, its the lowest volume of any phone i think ive ever owned, ive got to put the phone to my head, so its basically like making a call but using the back as an earpiece. thanks for the help.

I'm having the same problem with my phone, on any rom. According to CurrentWidget, the Ma being used by my phone will not drop below 150, even while idling. I'm starting to believe that my battery is faulty.

Are u guys calibrating the battety?

I thought I was, but apparently I'm not. Can you point me in the right direction?

Download the battery calibration app from the market. Charge to full run the app calibrate.....drain than calibrate again and you should be fine.

Upgraded to v2 and ran the battery calibrator. Phone finally lasts a day. Thanks. Am I supposed to run the calibrator at like 10% or should I let it die and run it after a 100% charge?

Battery calibration + managing screen brightness massively increases battery life. You need root to be able to clear battery stats, right?

I believe the calibration tools want you to use them at 100% charge. I got a chichitec 1900mA/Hr battery, calibrated (i guess it is now) and my phone went for more than 24 hours before hitting the 49% mark. This was with light use (checking email, checking web forums, playing some Angry Birds, and making some phone calls) but still a HUGE difference from the stock battery. Also, I turn off data connection via quick settings when I am at home. I do turn on wifi though while at home. Calibration ought to help out big time, as these phones are reporting a dead battery long before it is really dead.
Also, dont pay attention to the current battery monitor's report for standby current. It isnt accurate.

That's the one reason I keep going back to the stock setup I just seem to get better battery life out of is than any of the custom ones I've tried. I've only tried a couple. Has anyone found a ROM that gets better battery life than stock?

What's your Battery drainage - Your Average mA - Battery monitor widget beta APK!

Hi, I've been having battery issues with my sensation so I've tried all options in kernels and more but nothing seem to work for me. I would like to know how much mA (milliampere) our sensation should be draining depending on your setup of course.
You can find out using BATTERY MONITOR WIDGET or CURRENT WIDGET (enable log opt) they are free on the market and great if not the best tools for battery monitoring:
SEE POST ON PAGE 2 FOR THE BETA APK :')
PLEASE POST YOUR SETUP : your rom and kernel, if you're using 3g or wifi, having the sync on, animations, basically anything that would affect the battery.
Hope we can get and more accurate idea of what to expect with different configuration and find solutions so everyone can get the most out of their battery!
Edit: I've contacted the developer of battery monitor widget and he as accepted the invitation to come explain sharing a beta version that show the correct mA values for our sensation. NOW IM GETTING MORE THEN 12H WITH 70% SCREEN ON 3G AND SYNC...
Hi my name is DloBrown and Im A nightly addict who've been sober for too long!!!

I'm on Melvin's latest Beast rom and Faux 0.1.2 N_1.56ghz kernel with 3g and sync always on, screen set to auto, animations off and 5 homescreens full of widgets... I have an 1730mA evo 3d battery and I get about 300mA on average and 150mA screen off that about 6hours of heavy heavy usage
Hi my name is DloBrown and Im A nightly addict who've been sober for too long!!!

Even in airplane mode over night I'm losing about 200mA on average and like you nothing I can do seems to be able to change this fact. According to the Enlarge your battery life post it ought to be less than 10mA.

Wow... I know I'm a heavy user but even on airplane mode??? On my desire hd I. Could get 8-30 mA while in sleep mode wifi on... It's seems the sensation don't sleep properly. In sleep mode still draining like crazy. Thx for your post!
Hi my name is DloBrown and Im A nightly addict who've been sober for too long!!!

Why is our battery history in spare parts doesn't show the "partial wake usage"...?

I'm on a Android Revolution HD 3.0.2 with 3G watchdog and JuiceDefender running constantly, data on only while the screen is on, nothing else is on and I get an average of 250mA losing. When I do smth with my phone, it jumps up to around 500-600. Lowest at 120 for some brief moments.
I am a medium user with some internet on the go [ which uses more battery because of the signal strength changing every couple of seconds ], a lot of calls [ a lot calling me too ], few sms messages, gmail syncing every 30 mins, a little gps and this kind gets me through the day about 15hours.
But when I use the internet fully for a whole hour, the battery drops down to about 55%,
Very unstable battery drainage.

Using Superlite 1.4 and the lowest mine has ever been is 120mah in flight mode (LeeDroid was 220 at lowest).
I've tried nearly every ROM now and can't get any more than 12 hours use. This is a real problem when you're away for 18 hours with no access to a charge point
Didn't use the phone at all yesterday (maybe turned the screen on half a dozen times for a few seconds) and it went to 30% in 18 hours.
Only thing I have running is POP email (15 minute pull) and the rest is stock.
No Wifi, no bluetooth, usually 3g.
Sadly, I didn't keep the stock ROM long enough to see how much it drains..... I just had to flash

Stock Rom stock kernel. I have 1850 mAh 3d EVO extended battery I just got. Drained it and charged fully. I got 19 hrs no sync brightness all the way up WiFi on the whole time 3 hrs of display time. Hour or so of call time. Moderate usage I think. Stock battery I would only get about 10 hours out of it.

I thought it was pretty common knowledge that all of those current reading programs don't report the current drain correctly on the sensation.

That's correct, theres no app currently out, that can show the correct mA drainage.
..I mean if it really drain 200mA in an hour overnight it should be dead after about 8 hours sleep - simple calculation ^^.

Oh I'm using both battery monitor and current widget... Only issues with reporting mA on sensation was in standy mode... I'm using a beta version of battery monitor widget and It's fix i've got more than 12h with 70% display...my phone got as low as 13mA in sleep mode!!! ... Got 3g sync, my 5 homescreens of widgets...I'm amazed first time I'm getting those numbers
I'll contact the app dev and ask I'm if I can share the beta version that he sent me because don't know what he did but it worked for me!! I'll post a screen shot later today.
THANK YOU for posting guys! Remember to put rom/kernel and screen shots if possible

Battery Monitor Widget - beta APK for Sensation devices
Here is a beta APK (official update over the week-end).
This will fix the wrongly reported mA usage during standby... 200mA in standby means 8 hours max on standby with a 1500mAh battery! I got 40+ hours of standby/use.
To take advantage of the update, you have to enable the 'mA corrections' in the monitoring settings! Indeed there's a bug on Sensation battery driver/hardware, and HTC doesn't seem to want to fix it! It's fixed on the Evo 3D though!
One more note, I don't recommend using both BMW and Current Widget. Current Widget is a nice widget but it consumes more than BMW. You can verify that using System Tuner recording feature!
In future posts, it might be a good idea to post screen shots of the graphics showing times with screen on/off!
EDIT: Pro users should have received the update through Market, if not just check Market manually!

Sorry...
Hi my name is DloBrown and Im A nightly addict!!!

I was concerned when I first started reading. I don't have the device yet, so I didn't know there was a bug with mA reporting (which should be very low in standby - like, less than 20). I'm interested to hear more people chime in.

The bug is actually in the kernel reporting the value... It keeps saying 200-300mA incorrectly even when you get a 1% drain every 3/4 hours!
The app is trying to work-around this issue to provide accurate reading no matter what. Only Battery Monitor Widget is able to do that right now!
Now, some are having battery issues... happens with every phones anyway!
For the Battery Monitor Widget Pro users, the update has been released on Market, so please feel free to report on the app thread or the app web site.
And report your Sensation's drainage here too

What's the benefit of it?

If you are having battery issues on a stock ROM. Check the htc sense sync interval under accounts and sync. Stock setting is "push", that killed my battery initally. I disabled it entirely and my battery life is great.

Best battery life among all the ics roms?

Hi. I had installed several ICS roms, mostly different versions and variations of CM9. Since I only got a battery life of 12 hours I'm wondering if anyone found a significantly better performance on their rom. Thanks.
Or tell me that all the ics roms are hungry for battery.

Everyone is different depending on their settings and/or usage. I normally get a full day to a day and a half off of AOKPCB and AOKP ROM. Do some research to change the settings and undervolt if you have to... Battery life all depends on how the user has the ROM setup.

This is the best I have gotten, this was running NunHugger's UniPorn build 37 I believe. I have enjoyed his ROM.. good battery life, good stability.
This was with light to moderate use, no wifi, sync set for max interval, no gps.
But I got almost THREE DAYS!!! On average I get about a day out of it with moderate to heavy use.

Read the following thread for more info about Better Battery Stats:
http://forum.xda-developers.com/showthread.php?t=1179809
It gives a pretty good breakdown of what you are looking at, and looking for.
Basically it will show you all your wakelocks, which would prevent your phone from going into deep sleep. Some are easy to track down, others are a little more difficult. The dev of the app is also really helpful with looking over logs and helping track down unnecessary wakelocks.
For me, hotmail, weather widgets, facebook, use network for location and my data usage tracking app were the biggest battery hogs. I've since set up my email to sync only when i tell it, instead of auto-sync. Set the weather widgets to update at the max interval. Uninstalled facebook app, cause i don't have a facebook. and turned off use network for location .
But my data usage tracker (my data manager app) has a feature of "persistant notification". It is to keep a more accurate record of my data usage, but the tradeoff is that my number of wakelocks come mostly from this app. I'm currently looking for a data usage app that doesn't cause so many wakelocks.
If I know I'm not going to use my phone for a bit, I will turn data off. I also have my phone set to turn off wifi when locked. I have to wait for a few seconds for it to connect again, but it's not a big deal. I also turn off the phone's auto sync and background data, in the settings menu. I usually sync them about once a week or so.
So, the app doesn't do any "fine tuning". It just tells you what's keeping your phone up, using battery. The "fine tuning" comes from you.
I hope that helps

Thanks skyliner33v , for detailed explanation.
I will check my wakelocks.

IS these stats are fine??
deep sleep it shows as 0s.
As of now, I am charging my phone, I will fully charge and then check the stats again. roughly how much time i should wait to see the stats?

RemICS-UX is the best
I installed RemICS ROM and believe me with all the apps I have installed I find the battery life awesome with high quality graphics....

Dark Knight Rom ICS . since its black and white it saves up a lot of battery

I have try around 5 roms and Emacipation has the best battery life imo.

emancipation is a GB rom, not ICS.
so far all ICS roms have been brutal, especially for standby usage.
My phone just died with under 30 mins of screen on time because of standby drain. No rogue apps, no wakelocks, no poor reception, nothing.

JB's rom used to be perfect in battery life, until my installing apps the battery life drained to 12h, it's pretty awkward that I need to swap the battery at least sometime a day since my up time is about 17 hours.
It does not make a significant difference between standby and usage. The 100% battery before I sleep usually drop to 70-80% when I wake up.

[Q] Sensation battery and overheat problem

When i was using stock HTC sense in my sensation i faced the following problems;
1)Very fast battery drain if i browse the internet or use any applications(battery falls by 1% every 1-2mins)
2)when battery is 100% after just playing for 5-7mins(plants versus zombies 2) the battery falls by 25% to 75% thats a huge drop.
3)And when playing games just within 5-7mins the phone overheats abnormally
4)the battery part is not very hot but the bottom part below the battery slot is very hot(mostly when playing games)
I rooted my phone and im using vipers 3.1.2 rom but the problem still presists
the battery readings are not accurate most of the times for example sometimes when i have use the phone for a long time the battery still remains the same but after a while the battery drops significantly every second.
My question is is this a battery problem or is the motherboard/cpu of the phone causing these problems.
there is no expert in my country where i can get technicians to check the problems so ur advice is highly appreciated.

How old your battery is? Are you using any third party battery like Anker or Mugen?
Battery stats miscalliberation is a common thing and almost all of us face this issue after flashing a custom ROM. I guess you should give some complete charge cycles and it will get back to normal readings.

Mine after 2 years was in such bad shape that the phone kept dying ~5 mins after opening FB, and that is with low brightness, underclocked. Also the battery itself became bigger, instead of being flat it became... how do I put this... chubby I figured it's because of overheating.
Anyway, switched to Anker, it's much much better now.

I am facing overheating problem
I am facing overheating problem on my htc sensation xe. I am running vipers 5 rom with 1.5 GHz (standard frequency for htc sensation xe).
What I have observed is, whenever phone overheats it eats lot of battery. My battery is only about 2-3 months old. Any work around for over heating problem?
