Your Android phone battery may drain quickly, this might be due to bad battery health or some apps and games on your Android phone that consuming too much battery. You can check the battery health condition from a hidden test menu of Android. Using this Android test menu you can check different Android hardware information that is not available in normal Android OS interface. From this Test menu you can check detailed technical network information and diagnose problem, usage statistics of built-in and installed Android applications, WiFi information and of course Battery information as well. In this guide you will see how to check Android phone battery condition from hidden Test menu.

Check Battery Health Android Phone

The Battery Health screen includes information on maximum battery capacity and peak performance capability. Maximum battery capacity measures the device battery capacity relative to when it was new. A battery will have lower capacity as the battery chemically ages which may result in fewer hours of usage between charges.

Since users usually keep their AC adapter connected while using their laptop, the battery is often in a state of high-power(98-100%) for extended length of time which causes a reduction in battery life. So any battery health measurement you see could miss the mark by as much as 10 percent. Consider a concrete example. Imagine your battery had a brand-new capacity of 3000 mAh. Today, your battery holds 2880 mAh. Your phone reports this as “96% battery health” because your battery can now only hold 96 percent of the original capacity. I know on newer phones, running iOS 11 or higher, the way to check battery health is: Settings Battery Battery Health. I don't know if the same feature is available on iPhone 5s. For the most accurate test, schedule an appointment at your Apple Store Genius Bar and they can run diagnostics on your phone for you.

Having battery troubles? Yeah, we hear you. Almost everyday, we receive calls and comments about batteries that 'won't hold a charge' any more. Maybe you've been in that boat before. To clear up a misconception: a battery isn't like a water bottle. You can't use up half now, and then wait and use half later. It's not a tank of electricity. Also, batteries don't 'leak' power like water can. What we're dealing with here with a lead acid battery is a plastic box that encases a delicate balance of chemicals which are ready to interact with each other to produce electricity when the load is applied.

If your battery is having trouble producing electricity, chances are, it's a chemical issue.

How to test a battery:

Here are some ways to test your battery at home, and determine if it's bad

1) Inspect the Battery

Sometimes you can tell if your battery is bad by simply taking a good look. There are a few things to inspect:

• Broken terminal
• Bulge or bump in the case
• Crack or rupture of the plastic
• Excessive leaking
• Discoloration

Broken or loose terminals are dangerous, and can cause a short circuit. If a short did occur, there would be some indication of burning or melting. When a battery short circuits, all of the power is unloaded in an instant. That produces a lot of heat, and sometimes even causes the battery to explode.

If the battery is still intact, but there is a bulge in the case, this is usually a result of being overcharged. Others signs such as physical openings in the case are often caused by mishandling. Cracks, splits, and holes will not cause a battery to stop working, but for safety reasons the battery should be labeled unsafe to use.

With wet-cell (flooded) batteries, water levels have to be maintained. If they are low, usually refilling them with distilled water will help. But if the battery has been dry for a long time, it can cause a problem. When the plates in the cells are exposed to oxygen, it rapidly causes sulfation to build up. Sulfation is the number 1 cause of early battery failure. Plus, charging a dry battery will burn it up. If your battery has plenty of fluid in the cells, but the color is dark, or brownish, this is also an indication of a bad battery. Even if one cell is brown, it is rendered useless and therefore the entire battery is, too. Time to replace your battery!

2) Take a Voltage Reading

The voltage of a battery is a good way to determine the state of charge. Here's a handy table with the breakdown:

If your battery is:

• Reading 0 volts, chances are the battery experienced a short circuit
• Cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell
• Fully charged (according to the battery charger) but the voltage is 12.4 or less, the battery is sulfated

Sulfation is the natural byproduct when the battery discharges. Naturally, re-charging the battery will reverse the sulfation crystals and turn it back into electrolyte, ready to produce power again. But if a battery sat, uncharged, severely discharged, and/or drained for extended periods of time, the sulfation will increase in size and harden onto the plates. This covers the surface area of the plates, removing the chemicals needed to produce power.

Sulfation decreases the potential to reach a full charge, and it self-discharges the battery quicker than normal. Charging a sulfated battery is like trying to wash your hands while wearing gloves. At this point, charging alone will not restore the battery to a healthy condition. The majority of replacement battery purchases occur when the original battery has reached this point.

3) Load Test the Battery

Your local automotive shop is more than able to load test your battery for you. But it's quite easy to do at home. All you need is a digital voltmeter. For any load test to be accurate, the battery must be fully charged. Let's use a motorcycle battery for an example:

1. Remove the seat and expose the battery in your bike so that you have access to the terminals. Do not disconnect the battery because you will attempt to start the bike.
2. Hold the prongs of you voltmeter to the correct terminals on the battery.
3. Now push the start button and watch what the voltage drops to. It doesn't matter if the bike starts or not, what you're looking for is a voltage reading.

A healthy 12 volt motorcycle battery should maintain a range from 9.5 - 10.5 volts under the load for a good 30 seconds straight. If the battery begins to hold and then steadily drops in voltage, there is a problem. If the voltage instantly drops to 0 volts, that is also a problem. We call this the open cell. On a new battery, this can be a result of manufacturing flaws, but it also may be caused by sulfate crystal buildup.

Under the intense heat of the load, one or more of the weld pieces connecting the cells is coming loose and separating. This will cut the current, and voltage will drop. When the battery cools off, the pieces will touch, barely giving a complete connection. This gives you a false voltage reading. Batteries with open cells may read fully charged in idle, but they fail under a load test every time. Once a battery reaches this point, there is no going back. The best thing to do is recycle the thing.

How to tell if a battery is bad or good: These 3 steps will help you test and determine if your battery is truly bad or getting there. Sometimes it's obvious if there is a failure, but other times it's not. Flooded batteries make it possible to simply look inside the cells and determine if the battery has a physical defect. But for sealed AGM and Gel batteries, it requires testing. The only tools you really need are a battery charger and a digital voltmeter. If your battery experiences any of the symptoms described in the steps above, then maybe it's time to replace the battery.
