Retrain your nexus one battery
 

Every so often its good to wipe your battery stats and start from scratch. To do this you must have bootloader unlocked with a recovery image like ra recovery etc.

1.charge phone full
2. Turn off phone, hold down vol down and power till bootloader comes up, use volume down to scroll down to recovery and press power to select it.
3.scroll to wipe and select it using trackball
4. Scroll to wipe battery stats and select it.
5. When done, power down phone and charge for a while after its green...
6. (Optional ) I also after that use it till it completely dies, then charge again full from 0 to 100...
That should do it and hopefully get some more life out of your battery if your having some bad battery times...

I might try this sometime soon. I've read about doing it but haven't tried it yet.

Re: Retrain your nexus one battery
 

I did it yesterday and am getting a nice notible difference...

Re: Retrain your nexus one battery
 

I was at 90% when I started this and the phone is off and the LED is still orange. Its been like 30 minutes...it shouldn't take that long to charge 10% should it? Especially with the phone off.

EDIT: Nevermind, just turned green :)

Re: Retrain your nexus one battery
 

i will try this out today.

Re: Retrain your nexus one battery
 

I'm not sure if my battery meter is accurate yet, but since doing this 2 hours ago I'm still at 100%. I've had wifi on the entire time, screen is set to auto dim, did a couple of texts and some browsing.

Before, even having the screen on for 2-3 minutes would cause a 1-2% drop.

I'm also using an AVS undervolted stock speeds kernel.

Re: Retrain your nexus one battery
 

Another hour gone by and I'm only down to 99%!!!!!!!!!

Re: Retrain your nexus one battery
 

Yea, I'm still getting great battery from this trick... ill do it every 1.5 months or so to keep it going strong...

Re: Retrain your nexus one battery
 

I don't think thats a good thing, only losing 1% in an hour. Thats not the way its suppose to be correct?

Re: Retrain your nexus one battery
 

Losing only 1% a hour is a good thing...

Re: Retrain your nexus one battery
 

let me rephrase it, i know its a good thing if that were accurate but that can't be accurate can it? Mindfrost did you notice a rapid drain after that? i'm going to have to wait till i go to sleep tonight to get that full charge, then when i wake up tomorrow i'm going to wipe the battery info.

Re: Retrain your nexus one battery
 

Not sure, I couldnt judge without using it myself, But it is real good on the battery, or it has with mine.

Re: Retrain your nexus one battery
 

yeah definitely trying it out tonight, thanks for the tip. When i was loading the cyonagen rom i saw that option but of course skipped over it. I will post results mid day tomorrow, as long as i remember to wipe the stats when i wake up. wake n bake :mrgreen:

Re: Retrain your nexus one battery
 

Lol.. Ahh yes, must remember that, and gotta love wake n bake..

Re: Retrain your nexus one battery
 

is this procedure relevant on all other htc branded android phones also? thanks guys

Re: Retrain your nexus one battery
 

hopefully someone like carladarla can chime in. My girl has a hero but i haven't had any reason to unlock or ever go to bootloader on her phone. This is my first android phone so my guess is just as good as yours. To be honest I think dragon and mindfrost are in the same boat as me, we've all been winmo users till the nexus.

Re: Retrain your nexus one battery
 

Yea, this is my first android device so I couldn't say, but I would assume that if your bootloader is unlocked and there's the wipe battery stats I don't see what could hurt trying...

Re: Retrain your nexus one battery
 

I agree, if you go to bootloader and its there, it will definitely work the same.

Re: Retrain your nexus one battery
 

thanks for the answers guys. i got a couple weeks till my incredible drops. just trying to soak up as much as i can before it gets here

Re: Retrain your nexus one battery
 

I'll have to test it tomorrow and see what a normal day is like. I didn't notice a rapid drain until I did a lot of phone calls, which is out of my norm.

After about 11 hours, I'm down to 68% with what I consider pretty heavy usage. Voice calls is my highest percentage now. I've had WiFi on the whole time, did some browsing and texting and probably 1.5-2 hours of phone calls.

Re: Retrain your nexus one battery
 

I'll be testing from a different perspective as I am a HEAVY user and pretty much never put my phone down, there is no way I can go a full day without charging. I'm even using my phone to write this message.

Re: Retrain your nexus one battery
 

Lol sounds like me... every Rep point or posts I got is from my phone... I rarely use my pc. I surf web from 100% to 0... I got another another hour of straight internet usage from this, a solid 6.5 hours from 5.5 ..

Only time I put it down is if I'm out, and even then I'm using it one way or another... I do know I could easily get through the day with moderate usage and in the next day easy with light. .

Re: Retrain your nexus one battery
 

So I finally have to put this bad boy on the charger. I got significant battery increase after doing this. Thanks for the tip.
