# SysStats Lite vs Battery Testing

The clearest difference is rating: SysStats Lite at 5.0 against Battery Testing's 4.5. SysStats Lite also leads on in-app purchases (none vs 1) and ads (none vs shown). Battery Testing's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (12K vs 1). On price and device support there is nothing between them.

Both are free to download. Battery Testing sells 1 one-off in-app purchase. SysStats Lite asks for nothing beyond the download.

SysStats Lite holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Battery Testing has 12K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 50% of SysStats Lite's written reviews are positive against 23% of Battery Testing's.

SysStats Lite ships an update every 3 months, Battery Testing fortnightly. The most recent releases landed on October 2, 2026 and October 11, 2026 respectively.
