Almost 2 hours screen and 75pc.

This means more than 7,5 hours screen time.

Even so, I'm satisfied.

(my previous phone was an Inew V3. So, you know what I'm talking about.. :))

Offtopic, but take a look at that:

post-1006077-14129578397429_thumb.jpg

Laek.17's AOSP 4.4.2 v3

1-2h call's per day, some chats, forums, web browsing, mails (4-7 times a day), 30-40 photos each day (only few using flash) and around 3 hours music on earphones at max volume today on travel to/from work.

I use CM Battery Doctor, brightness: auto, 2G only, WIFI only when needed.

There's no way that battery still has 41% left. Check the voltage with some app like Battery Monitor Widget, if the voltage is below 3.6V then put it on charger immediately. Li-Ion batteries get damaged if they're drained below 3.6V, that's when the phone should show 0% (100% is 4.2V, although this phone has a magical battery that charges to 4.33V).

It's interresting. I've made some checks at kernel side.

Indeed it's set to PowerOff when battery voltage goes down to 3.4V! The same voltage is set to allow switch on the phone:

root@Coolpad8297:/ # cat /sys/bus/platform/devices/battery/Power_Off_Voltage
3400
root@Coolpad8297:/ # cat /sys/bus/platform/devices/battery/Power_On_Voltage
3400

Unfortunately it doesn't allow to change it using /sys/... tree.

root@Coolpad8297:/ # cat /sys/bus/platform/devices/battery/power_supply/battery/uevent
POWER_SUPPLY_NAME=battery
POWER_SUPPLY_STATUS=Charging
POWER_SUPPLY_HEALTH=Good
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Li-ion
POWER_SUPPLY_CAPACITY=31
POWER_SUPPLY_BATT_VOL=3974
POWER_SUPPLY_BATT_TEMP=310
POWER_SUPPLY_TEMPERATURER=6162
POWER_SUPPLY_TEMPBATTVOLTAGE=481
POWER_SUPPLY_INSTATVOLT=3974
POWER_SUPPLY_BATTERYAVERAGECURRENT=1004
POWER_SUPPLY_BATTERYSENSEVOLTAGE=3974
POWER_SUPPLY_ISENSEVOLTAGE=4036
POWER_SUPPLY_CHARGERVOLTAGE=4749
POWER_SUPPLY_STATUS_2ND=Not charging
POWER_SUPPLY_CAPACITY_2ND=50
POWER_SUPPLY_PRESENT_2ND=0

and power supply provides 4.73V:

root@Coolpad8297:/ # cat /sys/bus/platform/devices/battery/power_supply/battery/ChargerVoltage
4730

Isn't it too high?

 

Besides that it looks like kernel supports "wireless" charging (anyway, I would expect that there is hardware for it in our phones):

root@Coolpad8297:/ # ls -l /sys/bus/platform/devices/battery/power_supply/     
drwxr-xr-x root     root              2014-10-10 17:57 ac
drwxr-xr-x root     root              2014-10-10 17:57 battery
drwxr-xr-x root     root              2014-10-10 17:57 usb
drwxr-xr-x root     root              2014-10-10 17:57 wireless

That 4.73V is probably the minimum charging voltage since the charger should supply 5V. Practically any phone can support wireless charging if you can buy a convereter kit for it (which is just a thin flat coil and maybe some circuitry) that goes between the battery and the back cover, like this (that tab goes between the battery's and the phone's pins):

We just have to wait for one that's made for the F1 :)

I saw something like that before. GPS can

be fully functional without gps.conf on certain

systems.

well there is no gps.conf file in the rom zip either!Do you still have the rom zip?Can you check yours?

There is no gps.conf file in the rom zip. Probably, it is created by an apk (i did not use fastergps apk but once, i used gps test plus..

You really want to screw up your battery don't you?

Testing to the limits..

Well, gsams voltage meter is accurate.

Persentage reading is a mess.

BUT, 9:30 SOT is absolutely correct cause i spent the whole last night messing with messenger, spotify, web surfing in order to keep the screen on.

@Jpower73 please stop uploading sc in that way, you just f@k up our data

with many roms out there we all have ~2days battery life with ~4-4,5 SOT and using our phone

we all tested it, i make a repack from a version of it but i droped straight away

airphone who built it is not using it and from what i read you are the only one who use this rom

there is no way that you'll make me to use that crap, so once again please stop uploading sc like that and learn how to do it properly  ;)

and you MUST do a order for battery replacement yesterday  :P
