Hello last time when i was running Nessy#Fenice rom, my battery life was great, it could last for 4+ days without switching off my phone.
then one day i flashed another rom and wipe battery stats and the battery was no so great so i flashed back.
HOWEVER, i realised that the battery of the Nessy rom became horrible as well and was like dropping 2% every 30 mins! can someone help?
And also i would like to know which rom has the longest battery life? i only use 2g and occasionally 3g and i use my phone for texting and sometime go on wifi thats it thanks

Did you wipe the cache and the dalvik cache? After a rom flash, you should wipe the battery. Plug in your charger over night, next day you must have 100%, else you unplug for a second and charge again. The battery is full! Let the charger pluged in and reboot into recovery. Wipe the battery stats reboot and disconnected the charger. Now use your phone normally, run down to 5% and reload fully.
That's it.

If the ROM you are using is 2.3, then you can expect lower battery then on 2.2 while using 3G.
Install battery calibrator from market, charge to 100%, wipe battery stats and then use as normal. This should help a bit.

should i wipe battery stats i switching from extend. battery to stock. or only when switching roms? when does this matter?
[Also i know this doesn't belong here but my PC is really slow do easiest way is to ask: is there someway to search all my posts at once as they're becoming hard to keep track of ?]

I switched back to my stock battery after my extended died. I wiped battery stats, wiping stats when flashing new roms is recommended.
Wiping battery stats is never really considered an essential thing to do no matter what. It is nice though to do. I suggest it when you start realizing crap battery life on one ROM/kernel compared to the last one. The suggested way is to wipe it after installing a new kernel and as well as when you swap batteries. Other than that, really no need to in my eyes.
I wipe after every new ROM install, period.

This is when I do it also.
Digging up a thread here, didn't want to waste a new one.. But I have the OEM Extended Battery and I tried wiping my battery stats.. Charge full, reboot into recovery, wipe stats, unplug.. After this I noticed that my battery said 93% even tho the charge light was green.. I drained it until it turned off and charged again overnight.. In the AM, light was green, i turned phone on and its still showing 93% even though it was green. Any ideas? Did I lose that 7% forever?
Sometimes wiping the stats causes a bad battery read. A few reboots should get you back on track. If that doesn't work, try a full battery drain then a full charge. Let us know.
Will try that, even tho I kinda did already. I'm hoping with a few battery cycles the problem goes away.. What Im hoping is I don't need to bump charge now every time like I did when I had my inc

I doubt you lost anything. It would be like Spinal Tap having an amp which only went to 9.
I only had to wipe when my battery wasn't decreasing in percentage. After I wiped, it started decreasing like it should. I would think any fast reduction in percentage would be a bad battery.
Are there any proven facts out there that it is really ever necessary to wipe them? It's not like it actually improves battery life am I correct?
as far as wiping battery stats goes.
i have only used it when reconditioning a battery.
ie if you start noticing bad (read: worse that you have been getting) battery life after flashing a new rom or kernel. or just after a time using a standard rom.
what i do is
1 turn the phone off.
2 charge it on AC until it goes green and for an hour afterward.
3 unplug it and wait 30 seconds.
4 plug it back in and repeat step 3 until the light goes from red to green within 20 or so seconds. (this is called bump charging)
5 boot into CWR and wipe battery stats. and let it burn all the way down until it wont even turn on (flashing orange led)
6 charge to full and enjoy your maybe improved battery life.
when wiping battery stats, do i have to do it a few times or no? i wiped battery stats at full and drained battery until it turned off twice.. once wiping the stats with CWR and once, and after a cycle, with the 'battery calibrate' app (made by someone here on xda i believe)..
seems to be working okay i guess, but lets say i have 94%, i reset my phone and it comes back with only 84%.. it appears it's still reading my battery wrong by around 10%. is this normal?
It doesn't happen at every reset, looks like just the first one of the day. I guess I can charge to full, reboot, and charge to full again as a workaround.

i meant to ask this before but I forgot, can anyone try to do that and let me know if it happens to them too or if its just me
Charge with phone on until full then turn it off and charge.. about how long does it stay amber?

Hi all,
I have a question about battery life on the Simply Honey 2.7.2 ROM
My phone is usually idle overnight, but i notice a drop of about 25-30% in 8 hours. Is this usual?
Here are some screenshots
Battery Plot (1.26 am to 9.26am) Battery was 100% at 1.26
System details
Top Apps
Is this pretty normal for overnight battery drain? The Device usage indicates almost no use..so i'm wondering why the battery is draining.
Any help would be appreciated.
Thank you
I'm having the same issue. With Darky's 9.5 the phone easily last a day, now it's lasting 9 hours or so. I just flashed the new ROM yesterday.
This is from the Simply Honey post:
HOW TO RECALIBRATE YOUR BATTERY (by heartagramm):
COMPLETE GUIDE!!!
You'll have to use the phone for about 1-4 days (although it varies depending on the phone and battery used; every phone is an individual). It runs out of battery. Yes. Let it run. Recharge. After 3-4 recharges the battery will "gain" it's performance back.
After 3-4 full charge/full drain -cycles, do the following:
1. Charge the battery up to fullest.
2. Keep it plugged in to charger, and reboot to recovery.
3. On the recovery, go advanced, wipe battery stats, scroll on to yes BUT Don't wipe them yet. When you're ready, quickly remove the battery cable and push to wipe the battery stats.
4. Reboot the phone, use normally. Let it run completely out of battery.
5. Charge the phone back to full. Turn off phone. Charge until it says 100% on the green bar and vibrates for full charge.
6. The Important Part. Remove the charge cable for 0-0.5 seconds and plug it back in instantly. Let it charge to 100% again. Do this 1-2 times again, so you've done this 2-3 times total.
7. Reboot to recovery, wipe the battery stats again as on the step 3.
8. After wiping the battery stats, plug the charger back in the phone.
9. Reboot to ROM. Keep the cable plugged in. Keep it plugged in for about 30 mins to 2 hrs. Unplug. Should say 100%, mine did for about 40 mins after it depleted onto 99%.
And this is the way you should really gain great battery performance.

I'm going to try this and hopefully it works.
Let us know if it sorts itself out after a couple of days...
Chris.
Thanks. I will try this.
I recently downloaded a Battery Calibration App from the market too (NeMa) and calibrated my battery using that..but I'll try this method also.
Let me know if you have any improvements also.
Thanks!

I switched to Doc's ROM and battery life is back to normal. I'll try Simply again after a few versions.

I don't think there are going to be new versions, because he's now doing some Gingerbread based ROMS.
Which one is Doc's ROM?
I'm on SimplyHoneyV1.0XE and have been for a couple of days. This is my first Simply Honey experience but I think this is the best battery life I've ever gotten on ANY ROM including stock. Given it is a little early in my test to determine just how good it is going to be but I would recommend you give it a try and see how it does on your battery.
P.S. My findings were based on the fact that after a 100% charge, light usage (2-4 phones calls, and several texts) for almost 10 hours I still had 89% of my battery. Pretty impressive if you ask me.

I'm pretty sure they perform the same function. When you touch the "Calibrate Battery" button, the app automatically performs all the steps mentioned (wipe battery stats, mainly).
One app you might try is Juice Defender. I've used it a few times, and it worked well when battery life was an issue for me (I've switched to Axura, and it isn't anymore. Neither with Bionix).
Hi all,
I once asked why the battery life on my Hero was kinda bad (< 1 day with a full charge), and I did as was described in this post. I downloaded the Battery Calibration App, charged to 100% and pressed "calibrate battery", let it drain the next day , waited for phone to self-shutdown. Then I plugged it into the wall-charger. After a few minutes I switched the phone on again (while still connected to the charger), and immediately after it booted it said it had a battery percentage of 40%. Let it charge to 100%, and immediately when I started using the phone, the percents started to wear down again very quickly (>10% in an hour). Next day I booted into recovery and wiped cache and dalvik cache and battery stats, but battery life still goes down pretty fast. Did something go wrong here? If so, what should I do to prolong the battery life?
When I go to settings -> about phone -> battery, the 2 things I see at the top most of the times are visualizing/screen or wifi. A typical day for phone use for me looks like playing a little game, browsing, using tweetdeck etc at times when I'm bored or texting, so I use it a fair amount of time each day. I just installed JuiceDefender, gonna see that that'll bring me.
I run Elelinux 7.1.0 latest version.
greets,
Danny
i have not used the app yet, but i advice you unistall the app and using root explorer go to the /data/system/ and delete the batterystats.bin file and restart the phone and let it drain down completely and recharge and you should be fine
hi guys. i've just flash a new miui rom on my o2x. and i found that the battery drain much faster than it was before. last night i had 14% of battery left on my phone, and this morning it shut down due to out of battery. so i pluged in my wall charger while my phone was off. and when it showed the green fully chargeed bar i disconnected the charger and boot my phone in to CWM recovery to wipe battery stats. then i reboot the phone into android and u know what? the phone show 100% of battery only in 3 secconds and then it show 1% left, please connect the charger. huh? what the f*** is going on? i connect the charger and the phone show that it's being charged? how can it charge a fully charged battery? and the charging speed is faster as light. it's has been charging about 15 mins now and it show 46% charged. may be google was wrong saying that batterystats.bin does not affect the measurement of battery level.
Seems to be a bug issue.
What i would do is reinstall the rom.
Wipe data, wipe cache, and wipe dalvik cache.
Make sure you wipe both at least 3 times then reinstall because sometime android doesnt get everything the first time.
If still fails flash a custom kernel.
These help adjust the phones hardware to correspond with the settings of your software.
good luck to you.
Ok I made a mistake.One day after I installed a new rom,I wiped the battery stats,and the battery was around 40%,after that I had problems with the battery.I mean to make it charge to 100% I had to wait for even 3 days!
So I changed the rom,and wiped the battery stats again,when the battery was about 50%.
The problem is now,I can't make it to 100% to calibrate the battery.I mean my phone shows it's charging and after 2 hours,it didn't add at least 1% to the battery.
So,right now I can't get pass 45% battery,because (probably),the phone is set that is actually the max it can charge.
This might sound stupid but I have no other ideea.The phone shows it is charging,but after 2 hours it didn't charge at all.I tried plugging it into a computer,or a wall charger,the same,the phone remains at 41%.
Is there anything I can do?
Wiping battery stats has nothing to do with your problem.

Try this - Flash a new rom, but wipe the battery stats before that. Don't wipe stats again after flashing :thumbup:
