I'll fill in till someone who does understand batteries comes along. But from the little physics I did, it is a small capacity battery only 1000mAH, which for a phone isn't a lot really. Depending on how you charged it would depend too on how quickly it charged, a USB to a computer would charge it slower, up to the mains and you'd have a higher current? Higher something which will mean its charged quicker as a result, a USB would put out less power.
The MaH stands for Milliampere-hour, it basically looks at "the electric charge transferred by a steady current of one ampere per hour" (Wikipedia) The less 'mAH's', generally the less time it should take to charge but the quicker it will drain, but that does depend on the battery etc, gets very confusing.
You also have the fact if you weren't using it it would have charged quicker compared to maybe another device you had before? The quicker it takes to charge, the less you'll use it while its charging!
Finally battery technology is advancing quickly, very quickly. A few years ago Sony made an MP3 payer that could provide 3 hours of music playback on 3 hours of charge. I have no solid numbers but its something like 80% of the charge is done in the first 20% of the time the last 20% takes the final 80%? Maybe exaggerated but similar is true for many newer devices.
The Curve has an all new battery and so I'd imagine RIM pumped a fair bit of research into it, a quicker charge time being one of the benefits
In short, its normal Its a smaller battery than normally put in Blackberries so its to be expected, probably because RIM aims the device at the younger demographic who want to be on the go and so don't want to be hanging around for a phone to charge!10-12-11 09:34 AM - It is quite disappointing to know that RIM really hasnt learned to up the ante with the battery for blackberries...I was just getting comfy with this whole battery life issue... I'd been using the phone heavily all day, and as I wasn't going out the next day (today) so I figured I'd charge it that evening and just leave it overnight.
It was done charging by 10pm and I used it for an hour before bed, downloaded 2 apps over wifi and then turned it (wifi) off right after, didn't even run the apps themselves, just a bit of texting. Bed at midnight and I got 2 emails and 1 fb message in the early hours of the morning the only notification was the LED. When I woke up the next morning (6am) the battery was on 30%, I'm not going to lie, I was shocked. I figured maybe it had just messed up but an hour or so of use and it physically shut down on me giving me the 'battery drained' message (7am).
From arikados report .400 isn't must better and I'm reluctant to waste time upgrading if it isn't worth it.
For clarification I have brightness turned right down, only vibrate in use when I'm awake, asleep I put it on silent, no vibrate, no social feeds, facebook doesn't update, neither does twitter and no IM'ing aside from BBM. The one thing I did forget last night was bedside mode which I normally do, but even then when I do that, its on charge.
The one time when i got brilliant battery life was when I turned 3g off and down to only 2g, but I would rather like to be able to use it as a 3g phone, that said its never been as bad as last night. I'm SURE its more of a software management of the battery issue so I'll hang around for a bit till someone releases a new software update, but not happy right now! 9 hours from arikados 37 though is an EXTREME difference! Also out of caution I deleted the 2 apps I downloaded, they were terrible free games anyways
Even with my field reports, the fact that it was only a slight improvement (only when I have everything turned off like social feeds) then my old 8530 curve, is just a disappointment in itself.
For your report, that is pretty strange. It shouldn't last ONLY 9 hours, especially when you are idle-ing a lot. I may do a couple more small field reports just to confirm the length of the battery, but with my two days field report, I did manage to last 50% one day after going out and idling, and leaving it out over night to wake up at 45% and then use that for the rest of the day (with msn signed on).
and yes, don't upgrade to .400.. lol its terrible battery. I'm not sure why some peopel that upgraded said the battery life is great... its not- its also got that bubble SMS issue.
I'll do a couple more field reports with this firmware... I'm surprised we havent gotten a new one yet considering the new torch and bold got some10-12-11 10:58 AM - np
I am currently still using .353. Its the most well rounded version so far- i dont get the bubble scrolling problem on BBM or SMS. .400 and .464 both have the scrolling problem (in SMS, when u scroll up to read past messages, it wont scroll back down to the latest or just tedious and annoying).
In terms of battery though, I haven't gotten to test .464, but i assume its not that much better then .353~ i used it for about an hour and it didnt drop much (just like .353). but thats hardly analysis. I'll only do reports with versions without the scrolling sms issue lol.
I recommend everyone use .353 for now.... though my battery life has been considerably worst lately because of WINDOWS LIVE MESSENGER's new version... drains like **** >

11-19-11 03:50 PM - @heplock, nope I do not experience any heating at the back what so ever. I even have soft hard case protecting my blackberry and it seems to be in great temperature all the time.
The SMS/BBM scrolling issue occurs in bubble-type mode only, and it happens when you scroll up to read past messages in a thread with somebody, and try to scroll back down- it gets stuck and wont scroll all the way to the recent message OR the whole scrolling through the tread is just messed up completely. If you can confirm it scrolls properly (in bubble-mode) in SMS and BBM on .464 I'd be so greatful!!
@ your field report, thats great! I also dont have any third-party software, kept everything OFF, no push except for SMS and BBM. For me, 7 hours of moderate use = 50% drained. If I idle for 7 hours (texting only a little bit), it could be at 90% only by the end of it. So I think we have pretty comparable battery life. I would like to try .464 sometime unless a new one that fixes all problems is released soon..
I am a heavy Windows Live Messenger/MSN user, so all of my field reports included me being signed on 90% of the time. Without it though, I could last a pretty long time. Foursquare also drains battery a decent amount lol, I always forget to close that app when I open it up.....
Facebook and twitter is A-OK. They dont drain much Unless you have it checking for feeds frequently, but i find that unnescessary.
My input for today
