My battery is alright, and can last almost 2 days, but while from 100% to ~40% it drains 'normally' , from 40% to 0% it drains real fast - about 20 minutes phone call. anyone else share the same problem?
Yeah, think that's nothing unusual. It goes another way too - like 10 minutes from 0% to 50% when charging then 2 hours to 100% for me. Just live with it. Using Galaxo [II5] - so have a question to IK4 users: did they improve it in that firmware?
The battery provides Android with a voltage monitor which can only be used to estimate the remaining capacity. To give an accurate indication, you'd need to monitor the amperage, and neither the battery/phone nor the Android OS have any provisions for that. So what you're seeing is an estimate, and cannot be assumed to be a linear 100-0 scale. Have you run the battery down entirely, then recharged it fully? The purpose of this is not to condition the battery (the new types don't need it), but to calibrate the scale. Try it a couple of times (yeah sorry, should take most of a week) and see if your problem lessens or goes away.
@sado: I have K4 --love it, relatively speaking--but can't really say about this item in particular. I tend to just suddenly realise that my plastic brain has flatlined while I was looking the other way, far away from a power plug.
See my other post on this here... http://androidforums.com/samsung-i7...oid-support-what-would-needed.html#post184602 Basically bewteen releases II5 and IK1, the following mappings were changed. The First column is the ADC reading (AnaloguetoDigitalConverter) representing the REAL reading of battery power remaining. The 2nd Column shows how for a specific ADC reading, how the pre II5 firmware scaled/mapped this to a percentage. The 3rd Column shows the values used for releases II5 and IK1 and possibly beyond Note that after II5 the effective battery power percentage reading will drop much quicker than before (for percentages 100 to 51, the mapping tabe is unchanged) The other thing is that this does NOT change the battery life, only the effective percentage value reported back to the apps, (and therefore your impression of the battery drain) ADC PreII5% II5% 1030 50 50 1024 49 48 1018 48 46 1012 47 44 1006 46 42 1000 45 40 994 44 38 988 43 36 982 42 34 976 41 32 970 40 30 964 39 29 958 38 28 952 37 26 946 36 25 940 35 23 934 34 22 928 33 20 922 32 19 916 31 17 910 30 16 904 29 15 898 28 14 892 27 13 886 26 12 880 25 11 874 24 10 868 23 9 862 22 8 856 21 7 850 20 6 844 19 5 839 18 5 834 17 5 828 16 5 823 15 4 818 14 4 812 13 4 807 12 4 802 11 3 796 10 3 791 9 3 786 8 3 780 7 2 775 6 2 770 5 2 724 4 2 678 3 1 632 2 1 586 1 1 540 0 0 0 0 0
Nice reference, qwerty! I'm a visual kinda guy, so I made this. Edit: Correct header: "pre-i5 vs i5&later" (oops)
you might wanna change the header on that - it's not a i5 vs k4, but pre-i5 vs i5 & k4 (+future releases?)
