Fast charging batteries, the good and the bad.
Fast charging of batteries is very convenient, but comes at a price on the overall battery life.
Especially wireless fast charging has bad consequences!!

Amoled and different colours powerconsumption
We all know that the screen eats a lot of power and the brighter the worse.
But it was new to me that blue is so much worse than red and green on Amoled.
And also that even almost zero brightness is rather costly

Android, DISABLE or uninstall more bloat on non-rooted devices (here an S8)
When normal uninstall or disable is not available for an app, we DO have a bigger axe for trimming devices, even un-rooted ones

More on hot devices, batteries and charging
I have written several posts regarding batteries directly and indirectly, especially this old one.
But here I tried to summarise and update it.

Blackberry Priv, on the heating
The BB Priv is often accused for heating issues. And indeed IF it is used intensively, it WILL heat.
The peak I have in recorded history was 48.5°C eight months ago on 2017-08-13 (on MarshMallow)
BlackBerry Priv, Almost EIGHT days stamina, no tricks, though light usage.
I have previously contradicted the claim that the BB Priv has a poor stamina, but here an even longer run.
This is a collage to contain the almost eight days (7d 20h), as the 3C Battery Monitor app can only show five days.

BlackBerry Priv, 5¼days stamina, no tricks. Display on 50m/day
The BB Priv has a pretty nice stamina, if it is not too infested with bloat (mine is debloated).
Though some complains that a 3410 mAh battery is too small for a phablet with a 5.4″ QFHD display, it is enough for me.
5¼ days on 96% battery
This is with no trickery of radios off or similar. 4G, WiFi, NFC all turned on. GPS off though. ADD: BT off too.

Android Battery (and more on apps) on Marshmallow
As an addendum to my old general guide on battery performance here, a few things are different in Android Marshmallow.

Ios 9 – 9.3.1 (+A lot on battery info) First impressions: Same shit with added bugs…
For me the most vital app is the Messaging app for handling SMS/MMS. There is a new version, but ALL the basic flaws are still there (see this) and new have been added, along with new features.
ADD: There are bug fix versions too, see below.
Android, “Battery use”, more than meets the eye
The “Battery Use“-app is part of the OS, and is located
Settings > About phone > Battery use
First here is a collage of screen-dumps (click to view) from it (see comments towards the end)

How to obtain good stamina on an Android phone
Summary
- This thread is general in nature, but based on my Xperia neo Pro.
- Xperia phones DO have good stamina if set up and used correctly
I can get 4½ days of stamina WITH 3G+WiFi+Virus Scanner ON - Set Brightness to 100%, and use widget “Brightness On/Off“,
Use On in direct sunlight only. - Set Screen time out to 30 sec.
- Use the app AdBlocker to block specific apps from data connection.
- Use the app WapDroid to only allow WiFi at specific geographical ‘points’. (By Cell-ID NOT gps)
- Have the phone at optimal position.
Place on the desk not in the pocket while working. - Exit apps if possible when you are finished.
- “Ads within Android apps found to consume 75% of the app’s power.”
- Avoid task-killers on the bloatware.
(The repeated killing and resurrection eats a lot of battery) - Avoid ‘clever’ battery-apps in the background doing more harm than good.
- Note that the percentages in Battery Use are based on estimates.
- Consider if you need background data traffic or not.
- The “Android System”-drainage bug!
- Finally I have a few tests , if the above did not do the trick.

Central entry point on batteries
(at least this is my intention on how it should end and be used)
It should give info about batteries, how the phone uses them, and (hopefully) with some good hints to how to get the most out of each battery (Life and Stamina). Many of the hints go for other hardware with Li-Ion batteries as well. Say Laptops, Toothbrushes…..
This thread is originated from SonyEricssons Xperia phones.

Summary
On problems with weird drops and raises: Try “Johan’s Trick” below once
The currently best advice I can give for the usage pattern is
● Try to charge fully and deplete to about 40-50%bc
● Once in a while drain battery deep to get calibration right
● Keep phone on desk/in bag, avoid pockets, to keep cool.
● Leave phone idle while charging (e.g. while sleeping).
Note that the ‘remaining percentage’ you see is an ESTIMATE not a measurement!
