Hi sailfish009,

Thank you for your suggestion.

I believe the manufacturers of the Flame device took into account the size and weight of the battery, as well as overall cost of having a larger battery, before making a decision.

Hi,

well if flame phone's price was $170 + (cost of 3900 mAh battery), i would buy it.

$170 phone with short battery life is no-good. their decision is wrong.

ps: i sent my feedback to mozilla team, thanks for the link.

if i power-off my flame phone at 100% charged state, and 12 hours later power-on 97% charged state.

I agree with you but in my opinion the CPU is what drains the battery so fast. I have a 5" mt6589 device with 2300mah which lasts two days so this flame should last more then one day considering its smaller screen.

i am using flame-kk [2014-10-29] git version.

usim with flame phone power usage getting improved! [WiFi disabled] 8:00 AM 100% power charged 9:00 PM 83% power remained!

this is very impressive.

Hi sailfish009,

Thanks for posting your findings. This is very exciting! There must have been a lot of optimization work done on the OS to bring battery usage back to being great. =)

However, please keep in mind that since it's a version under development, this battery usage may not reflect the final product.

Also, there are some applications that can eat up a lot of battery. ConnectA2 is one of them, even though it's one of my favorite applications.

Thanks,
