    I average about 12 hours before my battery turns orange. Haven't noticed much difference between .439 and stock OS.

    I average 12 hrs before my battery goes orange. Same as when I used the stock OS, on .439 right now, no difference between the two I think.

    Depending on the day I get 10+ hours. I'm a heavy user and on a droid I was getting 5-6 on same usage so I'm pretty happy with it so far.

    Between 12 and 14 hours of fairly heavy usage. It usually has around 20% left when I sit it on the charger. Pretty much the same as my old Curve 9300.

    So when you guys say hours of usage this is the total amount of hours your phone has been on ? Or the time you use up all the apps on your phone a day adds up to twelve hours include your idle hours too

    I got beyond 25h on one battery charge yesterday The OS says 22h18 idle and 1h3 of use. I'm surprised because the total do not match 24h.
    But to be precise on the week end I get a way better battery life. Last week end I got over 48h. Mostly because my phone mostly rest on my couch and only get 2G and WIFI but it is set like usual with 2G+3G+WIFI on.
    During the week my average is 5%/h so about 20 hours between charges. But I'll report back with exact digits.
    So far the best battery life saver is to switch to 2G+WIFI or 2G only. It doubles my battery life.

    I had my brand new 9900 on, fully charged, for less than a day with 3G+2G HSPA+ in an area with excellent reception, at most 15 texts, 15 emails throughout the day with lowest setting of backlight and no wifi/bluetooth/NFC. Ending up sending it back.

    I find it counterintuitive for RIM to switch to a smaller battery for the 9900, but I guess they put thickness above a better camera (with autofocus of which is bearable), and battery life (unbearable coming from a 9700).

    if i put my 9900 on 2G and 10% brightness, my battery will last SO MUCH longer than when its on 4G and 70% brightness (default settings)
    I got your email. Thanks for your advice.

    I compared it with connection settings that I am using with my current BB 9700. You could argue that they are different phones (i.e. one is touch screen, the other not, etc.), but I expected more by purchasing a new phone at least a generation ahead-- not less.

    Also, one of the reasons why I moved from a 9700 to a 9900 was because of the HPSA+ connection, a touch screen, more RAM and a faster processor. I expected similar battery life considering it was a BlackBerry, and hence why I compared it to my 9700.

    Pretty sure everyone is talking about time in between charges which includes the idle time.

    3 hours use today. 18 hours out of charger. 70 percent left on battery. If your battery life sucks I would suspect the battery There is a known issue of some shipping with bad battery

    Unplugged at 9 am this morning. Went to work, bbmd and texted alot, got a few emails, broswed the web for a bit, 2 half hour phone calls, and currently it's 11:50 pm and my battery is sitting at 60%. That's on 2G though. I honestly have no problem leaving my phone on 2G and then turning on H+ when i want to browse the web or something. I've got no problems if it gives me this great battery life.

    Off the charger at 8:00 AM, it will be 60-70% when it's plugged back in, usually around midnight or later. I do mostly texting, track time and some phone calls.

    What's your battery life in hours?

    About the smaller battery, if the 9900 had a 1500mAh battery instead of a 1230mAh, this would give us a 20% increase in battery life. Not nearly the battery life lost between 9780 and 9900. So I wouldn't blame the downsizing.

    I admit I don't fully understand waht you're saying. For the 9700, it it lasts for about 2-3 days. For the 9900 it lasted about 12 hours. I'd take the 20% increase in battery life over function, but RIM decided to take form over function. I did acknowledge other higher consumption features of the 9900 in my previous post.

    Also, in no way am I acknowledging that a full discharge is a good thing to do.

    I'm just comparing the charge of both battery. The 9780 battery has 20% more power. So I'm saying even if the battery size was the same the battery life would be improved but only by 20%. I'm saying this is not a problem with the battery downsizing but more with the power consumption of the 9900.

    A full discharge is not a good thing to do. But the battery must have a protection mode rendering the battery useless in the worst case. And the 9900 goes all wireless off when the battery is really close to be empty. So I wouldn't care much about not fully discharging the battery. And a full discharge is required to calibrate the battery when it's not living up to its potential so you should try full charge followed by full discharge.

    Usage is only one of several factors that will impact battery life.

    Running 2G vs 3G/4G, WiFi on/off (connected vs not connected while on), signal strength (this is a big one), frequency of auto-updates (facebook, rss, social feeds, weather)

    Need all this info to make any helpful and realistic comparisons.

    My 2 cents...

    I can make it through almost everyone one of my work days with ease. I also have a charger at my work desk and in my car if needed. I would suggest investing in the wall charger that charges your device in half the time, great for when you only have an hour to throw it on the charger.

    How long to fully charge your 9900? Mine takes 2 hours with the Playbook fast charger.
