In the comments to linked answer, it was brought out that batteries are not allowed to stay at 100% charge since it is harmful to the battery and the battery % rapidly drops to around 90% as explained in this XDA post. This is a precaution implemented by OEMs ( though not sure if all OEM's do that) Related to this is battery longevity on terms of Voltage per ...

There now is a hardware+app solution for that, it's called Chargie. https://chargie.org Basically, Chargie is a Bluetooth switch that is linked to an app on your phone. You set the desired level of charging, the app runs in the background and stops the charge at the percentage you set. *disclosure: I am the CEO of Lighty Electronics, we have developed ...

Of course your device requires power to run – whether you've set it for charging or not. Question is: Does it use more power than it gets by charging? Which depends on multiple factors: Your "power source". USB only charges with 500 mA (USB2) resp. 900 mA (USB3), A/C with up to 2 A. Your devices power consumption. Depending on what it's doing.

It's a scam. Android app cannot access physical battery directly. The battery file is just an interface for Android with value provided by the battery's sensor. Again, a sensor only reads data; it cannot write/modify anything. An article on Android Police explained this very well, Battery not working correctly? Well, just defrag it! It's all so obvious now. ...

There's usually a wrong conception on how these "numbers" should be interpreted. For example, your screenshot shows "Screen: 3%". So what does that mean? a. the screen ate 3% of your battery, thus reducing it e.g. from 100% to 97% b. the screen was responsible for the overall discharging by 3% – in this case, it "ate 1.8% juice" Hint: it's not a) – so your ...

Short Answer From battery health point of view, Qualcomm Quick Charge 3.0 is comparatively better than Qualcomm Quick Charge 2.0, since power used for charging is better controlled, resulting in lesser heat Quick review of concepts (optional read) Essential concepts are summarised here in bullet form.

Fast Charging can be achieved in two ways Hardware based Charging Qualcomm- Qualcomm Quick Charge 2.0 and Qualcomm quick Charge 3.0. Also see Fast Charging by Qualcomm 3.0- impact on battery?. This is the most popular, adopted by OEMs under various brand names Type C USB Charging- USB Type C Charging explained. Also see Android phone “charging slowly”: ...

Okay.. Got it :) The first thing to note is on Honor 6, my previous device , there was a single file I could play around with to stop charging automatically On Moto X play, there are two distinct files - one for disconnecting the charger and other for removing charging symbol ( In other words, you could stop charging and still have the charger connected ...

Many ways - all of course, need root. Without root, it's not possible and you can only be notified either by automation or using an app as suggested in Chang's answer Battery Charge Limit from Play Store. If it doesn't work directly, look for help in the XDA app thread. It doesn't trip safety net if you are using Magisk. I use this app currently (Bonus, ...

When you plug your phone into a PC, or other device that communicates with the phone, the phone uses a USB "Data mode", so to speak. In this mode, there is a 500ma maximum draw from the USB port. When you plug your phone into a regular AC wall charger, there is no data connection. The phone then uses whatever amperage is supported by both the phone and ...

This is possible on Android, at least on Lollipop. The feature is dependent on the Bluetooth headset sending the battery level in the right format. If the headset supports it, you will see an option in the settings screen for the Bluetooth device. The option will be right above the check-boxes for Call and Media audio. If you don't see this option, then the ...

can I have access somewhere and see what Google is collecting about my own usage and my own battery performance? Yes. Click on My activity to see what information is collected by Google regarding your app activities (if you didn't disable it).

Performance has nothing to do with battery voltage. The reason is that the flash memory is "worn" and therefore slower and less responsive. My Nexus 7 (1st generation) is also very slow now and I have almost no apps on it.

Firstly one needs to understand C-rate or charge rate. Quoting from the linked article C-rate is a measure that governs at what current a battery is charged and discharged. At 1C, a battery rated 1,000mAh charges at a current of 1,000mAh. In an ideal world the battery would be fully charged in 60 minutes. At 1C, the same battery discharges at 1,000mA. Li-...

Li Ion battery discharge is not strictly linear, (unlike a capacitor ). This ensures available power is utilised till the end of battery charge But it is fairly linear, more so at lower loads as can be seen from this figure, where C-rate or charge rate is the discharge/ charge rate Assuming your app is not a heavy power hog, it is reasonable to extraploate ...

Discharging is the opposite of charging. When you charge some electric component, such as a battery, you are storing potential electric energy in it. When you discharge that battery, you are reversing the charging process and using the potential electric energy to drive other electric components. Don't be scared, most of the time you are discharging your ...

Accu​Battery can notify you when the battery charge reaches a certain level. It won't stop the charging, unfortunately, but it's still worth a try. :)

This issue gets pretty clear by the second screenshot, which I will repeat here: Battery usage (click image for larger variant) Please pay attention to its lower half, just below the graph, and let me point out some details: Mobile network signal: This bar has no black, which means the radio was on all the time. Further, the colors indicate a relatively ...

I'm going to answer generally, since the same is true of any smartphone. There are broadly two kinds of colour screen used on mobile devices (smartphones, tablets, wearables, and handheld game consoles): LCDs, and OLEDs. LCD screens These change their opacity according to an electrical signal. But to see that change in opacity, they need a source of ...

I can say %99,9 of all apps that claim to fix battery, get you longer battery life, better CPU usage, better RAM management, are completely useless wastes of battery, CPU and RAM usage. That app is no different.

Yes. Phone does use power from battery when recharging. Although thats something which would more likely depend on how phone is designed, so it may not always be true... but most phones are this way. I am basing my answer on a test I did. I reduced the charging voltage while at the same time making my phone (my old Samsung Galaxy S3 I9300) use high battery ...

Prowler answers your first question well: "Why does this happen" -> Prevents data corruption. To answer your question "How can this behavior be overridden?" You can try: setprop status.battery.level 50 from a shell terminal. Note that bypassing the shutdown is 10x more risky than a battery pull. However, in a true emergency, benefit > risk. Why it's ...

One important consideration is the strength of signal, if you have a stronger 4g signal in your area, 4g may consume less battery... But fallback to 3g in non volte networks is really irksome... Sometimes I miss calls when I am on 4g and using data. 2g definitely has significantly less battery drain.. so I keep my phone on 2g and switch to 4g when needed. I ...

The coverage issue will have something to do with power usage. When comparing 5 GHz battery drain vs. 2.4 GHz, a lot depends on the coverage you are in with respect to each frequency band. 5 GHz (for the same power) lacks the range of 2.4 GHz. Objects (depending on material) can obstruct 5 GHz more than 2.4 GHz (sometimes not depending on material). So,...
