Lithie vs Battery Guru: Which Battery Health App for Android?

Battery Guru is a well-maintained battery monitor with more than a million downloads on Google Play. Lithie is our battery health app, built so that every figure says where it came from. The two share more ideas than most apps in this category, and Lithie is not on Google Play yet, so part of this comparison is simply about what you can install today. It is as of October 2026, and Battery Guru's facts come from its own Play listing.

Lithie vs Battery Guru at a glance

How do they measure battery health?

Closer than you might expect. Battery Guru's listing says it estimates capacity in mAh from your phone's data and your own charges, shows it next to the design capacity, and marks each reading Verified, Estimated, Approximate or Learning. It uses the phone's own health figure when the phone has one, and otherwise needs some use and often a few charges. It can read the cycle count from the system or calculate it.

Lithie calculates health in mAh and as a share of design capacity from real charges, partial ones included, so you never have to run the phone flat. It shows that figure next to the one your phone reports, with a plain note on what a gap means, and labels every number reported, calculated or estimated. An optional Full cycle charge, from near empty to full, gives its most complete measurement.

So both are honest about estimates. Lithie's difference is the side-by-side view: two opinions on the same battery, and a shareable battery report that helps when you buy or sell a used phone. For the built-in options on Pixel and Samsung first, see how to check battery health on Android.

Can either one stop charging at 80%?

This is the clearest difference. Battery Guru offers a charge level alarm at the level you choose, and its listing states that it does not stop or limit charging. You still unplug by hand.

Lithie Pro stops charging at 80% or the level you set. It uses the battery protection your phone maker built in where your phone has it, or controls charging directly with root. With neither, it can open a smart plug's web address at the limit. You can charge to 100% once for a long day, or pick full charge days each week. Holding at the limit shows as holding, never as slow charging.

What drains my battery with the screen off?

Battery Guru shows screen on and screen off time, deep sleep and time held awake, plus battery used by each app while it was on screen. Its listing is upfront that screen-off drain is shown as one total, not split by app. It adds a morning report of overnight drop and an alert when drain runs far above your usual rate.

Lithie Pro's wakelock view shows which apps kept the phone awake with the screen off, from Android's own records. You can restrict an app in the background, stop its background activity or freeze it, see what Android reads back, and undo it any time. Those actions use access Lithie sets up once through Wireless debugging on the phone, with no computer.

What about chargers and cables?

Battery Guru measures power going into the battery and notes that you can compare how much current different chargers and cables send on the same phone. It also scores each charge from 0 to 100.

Lithie's cable test takes about a minute and reads what the charger offered, what the cable let through and Android's own USB warnings. When the phone slows charging itself because it is nearly full or warm, Lithie says so instead of blaming the cable. Pro ranks your chargers and cables by the power that really reached the battery.

Where does Battery Guru win?

Fairly in several places. It is on Google Play now. It supports Android 7 and newer, so it runs on older phones Lithie will not. It has 10 home screen widgets, high and low temperature alarms, a charging screen with a clock, weekly summaries, PDF reports and encrypted backups. If you want a rich monitor today and do not mind ads or a subscription, it is a solid choice.

How do they compare on price?

Battery Guru shows ads. Premium is a weekly, monthly or yearly subscription that removes ads and unlocks longer history, older summaries and more, and you can also unlock it for 24 or 48 hours by watching ad breaks.

Lithie has no ads. The free version includes the live charge ring, battery health, a week of history, the full and low charging alarm, the cable test and Full cycle charge. Lithie Pro is monthly, or yearly with a 7-day free trial, or a one-time purchase for life.

Which should you choose?

Choose Battery Guru if:

• You want a battery monitor you can install today.
• Your phone runs Android 7 to 10.
• You want lots of widgets, temperature alarms and weekly summaries.

Choose Lithie, once it launches, if:

• You want no ads and the option to pay once.
• You want a charge limit that actually stops charging.
• You want to see which apps keep the phone awake with the screen off, and act on it.
• You want a charger and cable test that does not blame the cable for the phone's own pacing.
