Got my phone upgrade this week and was bumped up to a Samsung Galaxy Note 3. The Note 2 has now been inherited by No.1 Son, who is very pleased with his new toy.
The Note 3 has some very nice features (some being hidden by Samsung), which I won't bore you with, but the battery life in no better (and possibly worse) than the Note 2. The decision was taken to Root it (very easy with TowelRoot) and do some small modifications, especially on under-clocking the CPU, which is way over-powered at 2.3 GHz. Reducing it to 1.6 GHz has made no difference to performance.
I've overcome most of the battery life limitations by resorting, once again, to Tasker and creating profiles to:
- When on Wi-Fi, shut down mobile data; when not on Wi-Fi defaulting to Nos. 2 and 3 below.
- When not on Wi-Fi, launch mobile data every 20 minutes between 06:30 and 18:30 to check for emails (this could also be achieved by using scheduled synch, but data would have to be on 7 x 24 with the consequent battery drain).
- When not on Wi-Fi, but needing certain apps to function, to launch mobile data and/or GPS on opening the said apps and then switching them off again when the app is closed.
- Setting the brighness to either minimum or auto-brighness and then merely shaking the phone to instantly set brightness to maximum (moving the phone up and down resets to auto-brightness).
Those profiles should go a long way to getting a full 24 hours or more from the battery when out and about.
