[Q] Battery life question - are there different battery versions?

[Gadgetguy2005]

Hello all,

I have a brand new Galaxy Tab ( three full charges so far) - and I get quite different results re. battery life then others.

Then again: I read some posts with really long batt life, and others with shorter.

I have Gingerbread - Overcome RC1 installed, and I in about 1.5 hours use ( no 3G, some wifi, medium backlight; time spent mainly installing / removing apps, some games, some email and web browsing) I am at 75%.

When the unit is fully charged, after I switch it on it goes to 99% immediately (I see 100% maybe for less than a minute). This morning I am at about 65% battery life, with about 2 hours use. ( I have erased the battery stats after installing the Overcome rom).

When not using the unit for several hours (for example over night): I do a complete shut-down.

Now others seem to get significantly longer run times.

Is it possible that there are (at least) two versions of the GT, one with better battery the other one with weaker battery?

Or do I have a defective unit and should I try to return it? ( I am within the 30 days return policy, and could go for an exchange)?

Or is my experience totally normal, and the "really long" battery lifes are more the exception?

Or will my battery life get longer after a few more charge / recharge cycles?

I would appreciate any feedback!

Thank you!

People claiming better battery life are running custom firmwares, have their cpu moderated, and have pulled all kinde of tricks to achieve this.
Also, your battery has to "settle"

Thank you for the reply.

I am also using a custom firmware but no other tricks (slowing CPU etc.)

So my unit is then probably normal?

How long does it take for the battery to reach full capacity?

I think I will return the GT for replacement...

Another update.

Yesterday, I have done a full recycle ( fully empty the battery and fully recharge).

Today, when I started to use it, within 50 minutes the battery level went to 80%.

I have removed now all apps, all widgets etc ( factory fresh gingerbread) and I will fully charge and then reset the battery memory within CW.

Lets see how that goes... but I start to worry now as my return period has just passed ( 14 days from purchase) - so I may be stuck with a unit with a battery problem...

I would reccomend to stop delete battery stat everytime now and then. Another thing is please wait few cycles so battery will settle down as someone said. When I got my SGT for the first time I was quite worried that my battery drain so quick. Simple internet browsing over wifi last for 3-4h. Later on I found tha some apps sync itself constantly, name pulse, weather widgets, rss readers etc. Ive check the apps and disable auto sync. Also moving from 2.2 to 2.3 gives me huge boost and make battery last muuch longer.

Install the version beta2. The battery on it lasts much longer. I checked and returned to the beta2 since RC1. Only first JJ4, then JQ1 and beta2. My English is not good, so I apologize if I wrote something wrong

 

[Gadgetguy2005]

Wow. That is an interesting theory. I will definitely test: you well may be right. I have used beta2 only for a short time, but I think the battery did last longer...

In beta2 worked for 11 hours. The RC1 is less than 7 hours. A friend has the same. Both went back to beta2. Wi-fi enabled, much inernet ,radio, Google mail, mp3. Used on a single chargefor more than iPad

For me it has always been a big differens in battery life after a couple of weeks when the battery is performing better.
In the beginning with stock rom i barely got trough one day with heavy use.
Now its no problem getting trough two days of heavy use. Using Overcomes (rc1) latest rom.

Thank you. Lets hope you are right.

I would deffinitelly recommend going back to beta2 as in my case on rc1 I was able to get maximum 7-8 hours when switching to beta2 gave me at least 12 hours. At the moment when not extensively using the tab I am able to get around 60 hours.
ps1
as someone mentioned before pleae stop erasing batterystats.bin
ps2
Do not try to install beta2 on rc1 as it wil cause you a lot of problems. Start with jq1 at least and then beta2.

Hello,

I had the same problem too, but I have resolved it now.
I started by browsing this thread:
http://forum.xda-developers.com/showthread.php?t=986067&highlight=false+status

Then I opened up my tab and disconnected battery for 30 mins. Reconnect and close up and that fixed the problem permanently.

For some people, flashing overcome 2.0 rc1 solved their issues.

Hope that helped.
