I just got the 7500 milli-amp Zerolemon battery for the S4 and am doing my 2nd discharge. The first one was 'forced' as I played YouTube and other videos to drain the battery before I went to sleep so I could recharge it while sleeping. It definitely took alot of playing to drain it down to 2%. Upon receipt of the battery I charged it although apparently the proper protocol is to drain it of its partial-charge and then fully-charge. I went straight to a full-charge from about 60%; hopefully it doesn't screw up the 'memory' of the battery.
A few notices early-on:
A few notices early-on:
- When charging, you have to keep charging until the GREEN LED comes on, not when it says 100%. Actually, I don't recall seeing the green LED with the standard battery (maybe it was there), I just remember the RED LED being on and/or the charger saying 100%. Funny that I forgot after doing it a probably 100 times !
- On the 1st full-charge (after I had charged it from 60% to 100%) the battery suspiciously charged very rapidly, as if the indicator was reading the standard battery. Because some messages came across when I was away from the phone, it charged while the screen was lit up and the result was it took about 10-11 hours before I got back to the GREEN LED indicator. I'll try and charge it next time with me next to it so I can see how long it takes with the screen completely off but the S4 on and Wi-Fi on, too.
- The battery power remaining would sometimes go up as much as 1-2% after I would hit a button after the phone 'snoozed.' Reminded me of when batteries would get stronger, at least for a bit, if you turned the device off. I take this to be a result of the S4's internals being confused by the much larger capacity of the Zerolemon battery.
- The battery seemed to drain pretty quickly from 100% down to the low 90's (like 1%+ or so an hour). But then it seemed to drain at 1/2 that rate (or less) for about 2 hours or so when it was stuck at 87%. Again, hopefully the S4 is accurate at lower levels so if the battery has power left it doesn't say drained or vice-versa.
- Even though the battery is alot bigger, it's not unwieldly. I do miss the svelte thinness of the standard S4 and if I had to take the phone to work where I could re-charge during the day I would probably use the standard battery so the phone could easily fit in a suit jacket. But when going away to friends or family for a day or weekend....or going to the beach or a wedding or event where you know you will have a few hours to surf, it's better to have the extra battery capacity. This comes in handy when you don't have to drive there yourself and can use the phone on the way to and from the event. When you take into account the use during the car ride plus at the event, I sometimes would be dead before or early during the ride back home. The 7500 mh capacity of this battery will assuredly leave you with plenty of juice for all-day events.
