There are some reports that some users are experiencing Battery problems on their Phone. Petteri Järvinen conducted a Battery Life Test, He test the Jolla Phone, Lumia 920 (2000 mAH, iPhone 4 (1420 mAH) and the Samsung Galaxy Note 3 (3200 mAH) and HTC One (2300 mAH)
According to WPSailors,The test was done by running the phones for 7 hours on Airplane Mode, and then on standby for 6 hours. Järvinen does remind that this is by no means definite or scientific test. After the test Jolla had already dropped below 70%, while example Lumia 920 was on 100%.
The answer is lack of optimization, and the reason for that is the same why Jolla was delayed for almost half a year. As ST-Ericsson decided to stop manufacturing the SoC Jolla was going to use, Jolla had to do quick switch to Qualcomm. Meaning Jolla has not been able to do more optimizing between the hardware and software.
So the positive to take out of this is that battery life should only get batter after updates – WPSailors
Are you experiencing battery problems on your Jolla?
