Note 4. Battery

[jaedre]

I got my note 4 on Wednesday and it's battery would drain pretty quick when I'm using the phone, I would lose 5% in 10 minutes. The first picture confuses me with how much I have time left on battery. Please help me.

i think it may be the time used and your graph does not tell anything post another when you reach below 30% battery.

The graph says you have 99% of the charge left (the line above the one you circled). Of the 1% of charge used, Android system used 26% of that (or 0.026% of the total battery charge), the screen used 15%, etc. The total, if all apps using any battery were listed, and the numbers went to about 3 decimal places, would always add up to about 99.99% - which means that all the power used from the battery was used. In your case, that's 1% of the total capacity. (The percentages for the apps aren't percent of battery capacity, they're percent of total power use.)

I don't know where you're getting that 5% loss number - the phone hasn't used 5% of the battery capacity yet.

Malik, other than when conditioning the battery, you should never let the battery get below 40%. 50% is the ideal charge point for maximum battery life. Constantly draining the battery to 30% kills the battery more than twice as fast as charging it at 50%.

My Note 3, in normal use, lasts over 8 hours to 40%. If I have to use it heavily and there's no power nearby to charge it, I have a spare, fully charged, battery in a soft plastic case in my pocket to switch with. (If I needed still more power, 2 more batteries and a charger are about $25.) That's one reason I won't buy a phone that doesn't have a field-replaceable battery. My 10 year old V551 spare phone is still on its original batteries. I want the original batteries to be working at near new capacity when the phone is so old that it can only be used to make sure I can get and make phone calls while my main phone is being repaired. (The battery in my Motorola Micro TAC only holds about 25% capacity now, but it's NiCd - and it's 26 years old.)

If you lose more than a couple of percent an hour when the phone isn't doing anything, it's time to spend $10 on a new one.
