Well after 10 hours on, bridged to my bb and streaming internet radio the entire time and also alot of internet browsing i still have 37 percent remaining!!!

I k ow there are others that have had problems but I have always had good battery life. I use it off and on through out my work day for many tasks. Than in the evening I attach it HDMI to my TV and watch exactly what I want. So from 6:00 AM to 10:00 PM. At the end of a typical day I still have 20-25% battery.

I've been very pleased with the battery in my PlayBook. I purchased the PlayBook the day it came out. Right now, under heavy use playing games and surfing the net my PlayBooks battery will loose about 10% charge per hour.

I have great battery life, but every night I use the Digital Alarm clock app from AppWorld, my battery health decreases 1% =/

[greatwiseone]

I think they have done some tweaks to the battery life over the various OS updates. I find that OS2.0 is a bit higher on the usage side, but nothing drastically crazy.

The battery life is great on my playbook....it's just a shame my Bold 9900 can not last nearly as long...so I can not bridge unless I am near a USB to keep it charged.

Who listens to the radio for 10 hours?

I know, I'm surprised that review said the battery wasn't that good...

i was at work...had the radio playing while working all day. cant use the radio on my work computer.

i find the playbooks battery to be average at best. My 8900 will easily outlast the playbook while bridged together. I find i lose about 10% a hour, and dont get me wrong...thats not bad, but i dont feel like im using the playbook that much to be losing that kind of power. im hoping this improves with OS2 but i do think that playbooks battery life is acceptable right now

Its a brand new OS so im sure they have plenty of optimizing left to do

[rotorwrench]

I too have found my PB to have excellent battery life. I'm comparing to two other brand tablets we have/had in the house and the PB averages within an hour of the iPad2. iPad1 had better battery life than the 2. I'm good for a solid work day and evening of mixed heavy/light use.

[kennyliu]

You shouldn't be comparing the battery life of the Playbook to that of phones. If you compare it to other tablets, then it's about average as most tests indicate.

Wait, wait..the PB loses 10% every hour even on stand by? If that's true, that diffidently a problem they should look into.

no sir....i meant it loses 10% a hour while bridged through my 8900. the problem though is that its not like im playing games and what not....all im doing is browsing the web.

i just personally feel like there is much room to improve when it comes to battery life

It's been 4 days since I unplugged from the charger, used intermittently(15-20 minutes of daily usage of mostly being couch surfing) and now still at 65% now.

in btw, I bought a 16GB on the launch date and got a 64GB one lately, for some reason I find the 64GB version getting a far better battery life, also the above described usecase is for the new 64GB model.

thats all u use yours? 20 min a day?

lol mayb i have a problem, because i have mine on me all day. ever since i put the SNES emulator on it i cant put it down. dont even like using my laptop anymore ha.

We'll see what the new software does for the playbook though

[kennyliu]

Here is what I mean when I say QNX on the Playbook needs more power optimization (see the attached table*).

Compare the battery life of the Playbook (7 hrs) to that of the Galaxy Tab 7.7 (12 hrs). Almost the same form factor / size, with the Tab having a bigger screen and a smaller capacity battery (5,100mah vs the PB's 5,300mah).

I hope that OS 2.0 is more optimized and we will see some improvement in battery life.

Apparently the AMOLED screens consume significantly less power, so that's a hardware difference, and not something RIM can just optimize away with software updates.

[peter9477]

Also worth mentioning that the PlayBook probably has better battery life than the table in that article suggests. It sounds like they may simply have set the backlights at 50% without taking into account actual brightness levels. With the PlayBook having a screen that is apparently brighter than the competition at similar brightness "percent" settings, it seems it may be at a disadvantage in such tests unless they use a brightness meter to standardize the test.

[mithrazor]

Also you're comparing something that's well within bounds. Against something that has exceptionally amazing battery.

It was talking about that if iPad had the same size battery as PB. Or vice versa. It would be equal to each other.

Makes sense. But how much less does the AMOLED screen consume? Isn't the backlight the major battery power hog?

As for the brightness, you may be correct. But AFAIK the new Tab's screen is about 400 nits vs 600 nits on the PB. Is this (100 nits at 50%) such a significant difference that would explain the almost 80 percent battery consumption difference.

[kennyliu]

It was talking about that if iPad had the same size battery as PB. Or vice versa. It would be equal to each other.

iPad 2 has a 6,930 mah battery (31% bigger capacity than the Playbook's). But it also has the screen whose area is twice as big. So, if you had an iPad of the same size as the Playbook, the backlight power consumption would also be much smaller.

Besides, I am comparing two tablets with almost the same battery capacity and almost the same size.
