Hello,
I was just asking myself if you really need to be at 100% before you flash anything in CMW? Is there any proven point why you should do it or is it just a recommendation? If you flash with less than 100% should I do a battery stats wipe the next time I am at 100%
Thanks Matt

No, but i would recommend at least 50%. The battery will calibrate itself after a couple of charging cycles.

I've never bothered with that, personally... I always thought the battery recommendation was in case you ended up running out of battery partway through a flash. I don't think the battery stats are really affected (well, they haven't been on my phone, and I very rarely flash with 100% battery).
So long as you've got enough that it won't die during the flash, although 50% is a good guideline I guess.

Okay, thanks guys I was thinking the same, mobile odin also lets you flash until 50% so I thought probably it's just for protection to prevent the battery from dying during the flash.
Its really for the noobs whop will spend ten hours flashing and only then read the instructions .

i flashed mine at 20% and was ok

Hi folks
I got an s2 (my first android) and I upgraded the Fw from XWKE1 to XWKE1. I also used the guide on these forums to root the device using Odin and (I think) super root
Now the problem I have got is shockingly bad battery life and I would like to try some other firmwares before I return the phone.
The question I have, will I have ant issues going from XWKE2 to another firmware?
Sorry for the newness question but I really don't want to brick this pjone

One after flashing it can take up to two weeks for battery to recalibrate .
Two as you no longer have the firmware that came with the phone and its been rooted the shop can refuse warranty or to even take the phone back /exchange .
jje
I had the same problem, but a factory reset fixed the battery life for me again. There's a thread about it in the Dev section...
Thanks guys. I will check it out

Why wouldn't you suggest a factory reset or link him to guide which restores you to O2 branded FW? Talk about over reacting.

I see you pointed him in the right direction .
OP said he was thinking of returning the phone so its no overreaction to warn him that the shop may reject the phone .
Pointless flashing to O2 if its not an O2 phone .
Just plain bad advice .
Factory reset will not cure bad battery drain though it will do no harm .

Guys,
I found a thread on the developers part of this forum that helped me to restore to the original Fw and now the phone is bring reported by titanium as not being rooted.
Its such a shame really. Apart from the battery, this phone is perfect

Battery Faqs say
One discharge battery reset battery stats charge 100% then bump charge disconnect and reconnect charger a couple of times . Use the phone and battery should return to normal .Or just use it for a couple of weeks .
True yes based on a couple of hundred rom flashes .

Every time you flash a new firmware on the phone you have to root it again. Just follow the guide in the Android Development forum and it'll be rooted in no time.

Don't know how fast extremely is.. I used to get 12-14 hrs. on Simply honey with moderate usage (25+ calls, text , few hours on the web and very little wi- fi) If you aren't getting that recalibrate as the post said above.
Also, this is a Gingerbread ROM so the battery life isn't going to be as good as Froyo anyway.

If you have Simply Honey on it then you are rooted and free to flash anything. The first thing to do is go onto settings/about phone and see what version you have and then decide if you want to stay with a custom rom or just put it back to stock. There are numerous tutorial threads here and plenty of people willing to help you out.
Good luck.

Calibrate your battery!
- There seems to be a safety feature in Gingerbread or Samsung's version of Gingerbread that causes the battery to start draining when it reaches 100%. That said to calibrate your battery properly you must do it as soon as the battery full pop up appears.
- Download the app found here http://forum.xda-developers.com/show....php?t=1024867 and follow the on screen instructions.

The app referenced up there is really simple to use and works great.

I am on Blitzkrieg Gingerbread and my battery only lasts about 6 hours when I am not connected to a WiFi. I use the re calibrating app every morning, or when I have to recharge to 100%, and it does not seem to be helping any!!! I really do not want to downgrade to Froyo, but if that is what its going to take to get 14+ out of my battery, then I guess I will. Any suggestions?????

get to 100%
use a file manager
head to data/system
delete batterystat.bin or somtehing similar its at the top.
Delete that.
It has been said over and over again that on CM7 doing that helps, and it actually does, i never asked why just doing it helps.
I'm thinking its because its a 2.3 rom, buttttt idk.

I had the same problem on an older version of CM7 (and older version of honey). I went ahead and flashed the newer version, changed my modem and kernel, charged and re-calibrated...try that.

That will work, but the method I always use is to wip battery stats and let the phone die, fully charge, and then let it die again. After that, the battery will be much better.
This actually does what Viper is talking about. All it does is simply delete the battery stats. Some say it helps, while some articles have said it does not help battery because the stats help tell the phone how to use the battery to its full potential. Personally, when I switched to Vipers rom I used this then emptied/charged it, froze sense and all bloatware through ViperMod (control?) and flashed the SBC kernel. It has been on for 4 hours now, with reddit and texting, and it is at 96%. That is ****ing amazing.
I taped 2 batteries together and they calibrate well, thanks.
Haha sorry about the typo guys and thanks for the advice ill try it when I come back from work tonight and see what happens.

Before wiping bat stats should the battery be at 100 or close to it (seems like stops at 99) and then wipe. Also should I do this with your stock rom first and then apply the test 5 sbc kernal or can i do it with the test kernal already installed?

It means that when you flash a rom ideally the battery stats are also wiped and the phone needs to "relearn" battery usage stats, plus phones are notoriously bad at guessing battery percentage above 90%. If you just flashed a rom give it a week or so and it should get better.

In my experience.... sometimes. I know that's vague but I have personally seen my G2 act strangely after restoring a backup and conversely seen it go straight back to regular battery usage. Flashing roms and low level system partitions cause our devices to do some strange things, it is completely expected.

4 hours can be spectacular battery life depending on what you're doing for those 4 hours...so some more information on what you're doing could be helpful. The charging time on our phones suck, I don't think you can get around that one.

Thanks. Agree. This is what counts in the end. There are other factors that go by the hand with the user. for example, maybe there is one rom which more efficient when the phone is on deep sleep than when is awake, and then there is another rom that its more efficient when the phone is awake. Which should have better battery life? One may think "Easy. The one that handles deep sleep better." But that may not be true in all cases, if you use your phone A LOT, and you are constantly keeping it awake, playing games, surfing, reading, texting and doing more stuff, maybe the one that handles the awake time better is going to be the better choice, because in the long run, you are going to get more juice out of your phone. Just an hypothetic case though.
Is better to try all the roms around and try to be aware of what type of user you are, so you can make a better choice.

I would recommend that too. :good:
A way to compare battery consumption is to see how much the phone uses when idle. For example, leave the phone alone for 1 or 2 hours everyday and see how much it burned during that time. My phone averages from 0.3 to 2% per hour. Use this test with other ROMs as well. Also, at the end of days of extensive use (3 hours or more of screen on time), I average 5 to 6% per hour (Percentage of power used divided by number of hours since unplugged). If you've unplugged your phone 3 hours ago and you're at 75% --> 25/3 = 8.33%/hour.
Use the percentage of consumption in idle mode and the average consumption at the end of the day when comparing ROMs and kernels.
