Hello forum,
first of all, I'm unsure whether this is the correct place for this question, if it's not, please could you forward me to the correct place?
I have currently installed CM11-20140102 and I've noticed that the battery drains a lot compared to CM-10.x.
FWIW, I typically set my phone to use 2G data and I switch to 3G when I'm browsing the internet or playing. But since installing CM11 I've noticed that the battery lasts just half a day when only enabling 3G. After googling a bit, I found that some people [1] claims that the battery is astounding, which makes me feel odd about this topic.
In order to check this, I left my as much as in standby mode as I could (i.e. no activity or very little activity during the experiment) in the same place (so the network signal was about the same) but in three different conditions: no data connection (baseline for battery consumption), 2G only enabled, 2G&3G enabled. The attached screenshots [2, 3, 4] show respectively the battery status for those conditions. You'll notice that in [2], 20% of the battery was consumed in about 10 hours, in [3] 46% was consumed in approximately 10 hours, and in [4] 22% was consumed with 8.5 hours. Normalizing such numbers, we observe that
[2] no data connection, 20% / 10hours = 2% per hour
[3] 2G only, 46% / 10 hours = 4.6% per hour
[4] 2G&3G, 22% / 8.5 hours = 2,5% per hour
which is surprising. In CM-10.x, 2G was extremely battery saving compared to 2G+3G (sorry, have no numbers for that), however CM11 does not follow such behavior, which is very strange as 2G was supposed to be less energy consuming.
Has anyone experienced such battery consumption behavior?
Thank you
