Default Question for Mark Rejhon re: battery life

Please Login to Remove!

I have followed your tips for quite some time now. I am breaking in the battery in my new 8700 and am working on the first complete discharge cycle. How far does it have to discharge?? Until the unit turns itself off?? When you get the low battery warning??

BTW, I am down to 25% and have had it running since Monday afternoon. I have used it heavily and have had bluetooth on the entire time in order to run the battery down faster. I am please with the battery life on this unit.

Thanks in advance.

I have only had mine for 2 days, it shut itself off while I was setting it up Weds. night, so I charged it overnight. Currently after 1 full day, I am at 80%. I do have it set up to shut off automatically at 11pm and wake up at 7am. I get about 50-70 emails, did IM for about 30 minutes and browsed for about 30 minutes, 2 phone calls for about 10 minutes total, no heavy usage. At 20% per day maybe I can go 5 days ;)

Problem I see with that is what if you get a phone call. The device wont turn back on for that. Being on infinite call for all my firm blackberry's thats a bad thing. I still have to say leaving my 8700 on all the time and getting 30-40 emails, 1 - 2 calls per day I get great battery life. I don't have to recharge near as much. In the 7290 days I had a car charger for the 20 minute drive to work and a charger next to the bed for overnight, I was getting a day and half with the extended battery installed.

I doubt it. The OEM Holsters + Sleep Mode cuts the battery usage by an astronomical amount. I notice atleast a 50% improvement, if not 75%, from using the Holster all day to not.
And webmessenger has an almost constant data connection, which drains the battery too.

Ya but on my 7290, with Webmessenger on, i could keep webmessenger ON for 36hours and I would still have about 15-20% battery life.

So you think it's just me not using the OEM holster?

That would be my guess. To run the screen, lighting sensor et al takes a ton of battery.
though you you're not a fan of the holster, it could be worthwhile to try it for 1 day. You should notice a huge difference.
If you don't use the holster because you like to leave it on a desk....I find that if you place the magnet of the holster over top of the magic spot on the blackberry, it will turn the screen off, and maximize your battery life. when it beeps, just brush the holster out of the way.

i use the OEM Hydrofoam or whatever it is...the magnet is what makes the difference.
I really like leaving the holster on top of the Blackberry in the way I'd mentioned. It's also better than walking around an office with an "empty holster"...
The light is a huge killer too, and with the 8700 light sensor, I'd imagine the light would be on more often than not...but I can't really speak to that as I'm an outdated 7250 user...
I'd be interested in seeing what your findings are.

I don't know what you're talking about. Whatever holster you use, it has to have the magnet in it for "screen sleep". If you're using a leather holster without a magnet, then that would definitely be part of the cause of your battery drain. Not only would the screen be on all the time, but the light would be too...

I have never had my BB facing out in the OEM plastic holster, don't even think it will fit that way?

Look it is sim-ple go to an arts and craft store and buy a magnet (about the size of a dime or a nickel will do), I used electrical tape to secure it in place right over where the OEM would go and you are set.

Wish we had 'timed profiles'. I keep my BB out of the holster during the day because I have my profile set to vibrate+tone when in the holster, but tone only when out of the holster.

If I change the profile during the day, so that it does not vibrate when in the holster, then I need to remember to change the profiles all the time when I actually pick it up and use it.

Are there bad consequences to battery life if I leave it connected to the computer all day when at my desk? I think Mark's FAQ said that this was good for the battery, but I'm a little wary...

I have "timed profiles", works great:

7am-11pm vibrate
11-pm-7am off

;)

I just charged my 8700c BB for the second time 11/30 and 12/4, it seems to hold a charge as well if not better than my 7290. Since I have done more browsing on the 8700c because of speed, I am very happy with the battery life.

I'm a first-time BB owner and just got my 8700c

Should I:
A) Start using it right out of the box, kill the battery, and then do the charge/discharge cycles.

or

B) Fully charge up the battery, kill it, and then do charge/discharge cycles?

Thanks!

Best option. Don't forget to keep charging for a few hours after the battery meter hits 5 bars -- often 5 bar is still only 80% charge. (See Options->Status the instant power bar changes from 4 bar to 5 bar and you will know what I mean)

However, after full charge/discharge cycles, go into a habit of usually topping off the battery, with occasional full charge/discharge cycles to keep the battery sufficiently exercised. Lithium battery chemistry "prefers" being topped off as they do not have the memory effect.

I am charging mine for the 3rd time this morning, should have done it last night, but forgot, it was dead this morning. It took about 2 hours using USB to computer to go from 15% to 100% according to the options/status not the "bars".

I was alittle busy yesterday with yak-on that killed the battery a little faster. Not that yak-on uses excessive battery life, but it isn't "asleep" when I am chatting ;)

I am very pleased with getting at least 3 full days is great.
