GSam Battery Monitor show all the info you need for your battery.
Your phone says battery is at 40 percent. But how long will that last? An hour? Three hours? Depends on what you are doing. The default battery screen shows a list. Screen. Chrome. YouTube. But it does not show the full picture. It does not show wakelocks. It does not show CPU usage per app. It does not show signal strength drain. GSam Battery Monitor fills those gaps.

GSam Battery Monitor Tips that actually help
You can install GSam Battery Monitor app and see your battery stats in minutes. Finding the root cause of battery drain takes a little detective work. These tips help you get the most out of the app.
Set a custom reference time when you want to study battery use for a specific period
Here is a question. Why does your battery drain faster on some days than others? The answer might be in a specific time period.
GSam Battery Monitor tips from experienced users all say the same thing. Use the custom reference time. Select the period when battery drain was high. Review the stats for that period. A player who studies specific periods finds patterns. A player who looks at overall averages misses the details.
Check app level drain first if battery life suddenly gets worse
Battery life is fine one day. The next day it is terrible. Something changed.
Open GSam. Check the app usage list. Which app is at the top? A player who checks app drain first finds the culprit quickly. A player who ignores the list misses the obvious.
Use graphs to look for patterns in temperature, signal strength, and discharge rate
GSam Battery Monitor similar apps show numbers. This app shows graphs.
Look at the discharge graph. Is the slope steep or gentle? Look at the temperature graph. Is the phone heating up? Look at the signal strength graph. Is the signal weak? A player who reads the graphs understands the context. A player who only looks at numbers misses the patterns.
Pay attention to wakelocks and background activity if standby drain is high
Standby drain is the battery used when the screen is off. If standby drain is high, something is waking the phone.
Check the wakelock section. Which app is keeping the phone awake? A player who checks wakelocks finds the background drainer. A player who ignores wakelocks continues to experience poor standby time.
Try widgets or notification tracking for quick access to battery status
GSam Battery Monitor app has widgets. You can put battery status on your home screen. You can also see battery stats in the notification bar.
A player who uses widgets checks battery status quickly. A player who opens the app every time spends more effort. Widgets make monitoring easier.
On tablets, use optimized layout for more accurate long standby estimates
GSam Battery Monitor app has an optimized layout for tablets. The time estimates are more accurate for devices with long standby times.
A player who uses the tablet layout gets better estimates. A player who uses the phone layout on a tablet gets less accurate data. Use the right layout for your device.
Compare CPU and sensor usage across apps to identify hidden drains
Some apps drain battery through CPU usage. Others drain through sensor usage. GPS. Accelerometer. Gyroscope.
GSam shows both. Compare CPU usage across apps. Compare sensor usage across apps. A player who compares finds hidden drains. A player who ignores CPU and sensor misses the full picture.
If you use the Pro version, take advantage of advanced reporting and customization
The Pro version adds more features. More detail. More customization. More reporting options.
A player who uses Pro gets more value than a player who stays free. If you use GSam daily, Pro is worth it. The advanced features save time and provide deeper insight.
