AT&T 9810, what OS should I be on? Poor Battery Life

**Roveer** · 06-27-2012, 01:30 PM

I got a 9810 from a business associate and moved over from my 9800. It appeared to be on the latest AT&T OS so I did the swap using DM from my 9800. I've had quite a few unexpected reboots and I've noticed that the battery is lasting less than a day on light/average use. This morning I turned off wifi and by noon was already down to half battery.

I've read a bunch of things about possibly reloading the phone. Also, what OS version should I be on? Right now I'm on 7.0.0.583 which is what AT&T's website is showing.

I'd really like to improve the battery life and limp this phone along until the BB10 phones come out, but since I really want a physical keyboard I will likely have to wait until 2013.

Suggestions on how to fix this thing up for 8-10 more months of use?

Hopefully you did not device switch all your apps from the 9800 to the 9810 as there has been some compatability issues with apps from OS6 that will quasi run on OS7. Random reboots, sluggish behavior, and battery drains can be caused by this incompatabiliy issue.

Other things to check for would be frequency of updates on social apps (Facebook, Twitter) and apps like BeWeather.

The best OS is a personal thing. I would encourage you to upgrade to one of the 7.1 versions that are available. I am running 7.1.0.428 and have had no negative issues with it. Others do have issues.

Do not be afraid to load a "leak" or an "official" OS version from another carrier. All OS versions are created by RIM. The difference between a "leak" and an "official" is this: a leak becomes official when a carrier decides to approve it. The BlackBerry 101 section here at CrackBerry has step by step instructions for loading either.

As Newcollector mentioned, I'd upgrade to any 7.1 available. The .4xx series have had issues with mic problems-ie: mic not working in certain geographical areas. However, the .378 and .391 official releases are" issue free" and work great with long battery life and improved browsing, etc. light years ahead of the 7.0 version you are using now. BTW, that release that you are on now from AT&T has been known to have a lot of issues. It caused many problems for my wife when she downloaded it from .261.

As for the 3rd party apps, Newcollector is correct in that many of the old apps that worked on your 6.0-9800 were not compatable. You can go to your AppWorld/MyWorld account on your phone and click on "uninstalled" to see what has not moved over and why it hasn't. Sometimes it just needs to be reloaded via appworld and sometimes it's not compatable, but most are now. It takes time for developers to adjust and rewrite codes for apps to play nice with a new OS.

I have been on 7.1.378 since it came out in May and it is awesome with zero issues. It's from Mobilicity and I believe .391 is from Rogers. Both are in Canada but that means nothing. An OS is an OS, leaked or official. If you do not know how to upgrade an OS, let us know and we'll walk your through it step by step. That's what this forum is about--helping each other. Good luck.

Hmmmm I'm going to disagree with the others. I've tried so many OSes, most recently mecca els popular beta prime hybrid. Nothing has compared to the battery life I get on 7.0.0.474 when I turn off H+/4g. I've decided to stick with 7.0 precisely bc turning off 4g isn't possible with 7.1

I have 7.1 running and I have notice very little difference in battery life. I do go to Wifi at night now which helps a lot, other things mentioned here. The 9800 I had was much better on batteries but the performance of the 9810 is worth less battery life to me.

Play around with the settings - it will get a bit better.

I run 7.1.0.391 and I get quite good battery life. I use Auto On/Off with its default settings which makes it a big battery saver. I have BlackBerry Protect and BerryWeather as the only apps that hit the network on their own (apart from Messages, of course) and I do not use BBM - it's not installed.

I get 2 days (just) without a charge.

The 9810's faster processor chews through batteries quite fast. Ah ha, you have been using this. No wonder the battery is flat...

I also found that my original battery had a bulge on both sides making the back a really tight fit. Bulging batteries are failing batteries so I ebay'ed a new Genuine BlackBerry battery and I get much better battery life than with the old battery. It is worth checking you battrery for bulging.

One other little tip that I use is to keep my phone in the supplied holster.

Many new BlackBerry users may not know that The Blackberry has an unique feature that puts the phone to sleep when it is in the holster. There is a magnet in the holsteer and this operates a sensor inside the phone which shuts down the CPU (well, more or less), leaving the phone able to receive calls, emails, BBM, and other messages. When you remove it from the holster, the phone wakes up and works normally.

This saves loads of battery. Really lots.
