There are so many things I don’t like about the iPhone: you still can’t download apps outside the App Store (in the US), the typing experience is terrible, and it offers less customization than Android.<\/p>\n

However, the one thing I’ve always envied, at least since it was introduced in 2018, is the built-in battery health tool that tells you how much of your battery’s original capacity is left.<\/p>\n

Then, Google brought a battery health score to Pixel phones<\/a> with Android 16 in 2025. I thought Samsung would follow suit. But fast-forward to 2026, and there’s still no battery health tool on my Galaxy S24 Ultra. <\/p>\n

However, you can dig it out of a hidden log on your phone. I’ll tell you how.<\/p>\n

You may or may not have battery health in your Samsung settings<\/p>\n

My S24 Ultra doesn’t, and I’m not sure why<\/p>\n

\"a<\/p>\n

The battery health checker is such a simple but genuinely useful concept.<\/p>\n

Every battery is rated for a certain number of charge cycles before it drops to about 80% of its original capacity. The phone counts the cycles you’ve used and measures how much capacity the battery can still hold, then shows that as a health percentage.<\/p>\n

I recently learned that Samsung has had something similar in battery settings since One UI 7. But it’s not available to everyone, and I’m not sure why.<\/p>\n

You may or may not have it depending on your device, region, and One UI version. My US-model Galaxy S24 Ultra running One UI 8.5 doesn’t.<\/p>\n

The closest thing I could find is the diagnostics tool in Samsung Members that tells you whether your battery is normal, weak, or bad. But a normal battery could be at 99% or 82% health, so it really doesn’t tell me much.<\/p>\n

Thankfully, there’s a hidden way to check.<\/p>\n

\n\t\t\tI finally stopped letting my phone’s default settings limit me, thanks to this little-known Android power utility
\n\t\t<\/a><\/p>\n

I can now see the bigger picture of why battery drain happens on the system level<\/p>\n

How to pull the numbers from a hidden log<\/p>\n

You’ll need a PC<\/p>\n

\"a<\/p>\n

Samsung has a hidden SysDump menu that can generate a full system log with lots of information about your phone, including battery data.<\/p>\n

You can access it by turning off Auto Blocker<\/a> and following these steps: <\/p>\n

Open Settings, go to Security and privacy > Auto Blocker, and turn it off.<\/p>\n

\"Samsung\"Samsung<\/p>\n

Then launch the Phone app and dial *#9900#.<\/p>\n

Select Run dumpstate\/logcat and wait for it to finish (it may take a while).<\/p>\n

Tap OK on the Dump Result box. It’ll take you back to the initial screen.<\/p>\n

\"Samsung\"Samsung<\/p>\n

Select Copy to sdcard(include CP Ramdump). After a short while, it’ll show a success message.<\/p>\n

\"Samsung\"Samsung<\/p>\n

Open My Files and go to the log folder.<\/p>\n

Find and open the .zip file that starts with dumpstate_.<\/p>\n

\"Samsung<\/p>\n

Unselect all, select dumpstate.txt, and extract it. It’s usually a large file (mine was 235MB).<\/p>\n

\"Samsung\"Samsung<\/p>\n

Send the file to your laptop, then open PowerShell in the same folder as the file.<\/p>\n

\"Windows<\/p>\n

Paste the code: Select-String -Path .\\dumpstate.txt -Pattern “mSavedBattery”. It’ll pull up all your battery data.<\/p>\n

\"Powershell<\/p>\n

You must first turn off Auto Blocker before inputting the code because it blocks most dial codes. Also, this may not work on every Galaxy, as carrier-locked phones in the US often block the SysDump menu.<\/p>\n

You can open the dumpstate.txt file on your phone. But when I searched, the battery fields didn’t show up at all, even though they’re in the file.<\/p>\n

The likely explanation is that the phone only loads parts of the doc at a time (it’s over 120k pages), so the search tool can’t find fields much lower down. PowerShell on a PC found them right away, though.<\/p>\n

What the numbers actually mean<\/p>\n

You only need to pay attention to three of them<\/p>\n

The log lists a handful of battery fields, but these are the ones that matter:<\/p>\n

mSavedBatteryAsoc: your battery’s current capacity as a percentage of its original capacity. Mine was 99.<\/p>\n

mSavedBatteryBsoh: Samsung’s battery state of health estimate. It’s the equivalent of the iPhone’s battery health. Mine was 98.<\/p>\n

mSavedBatteryUsage: your cycle count multiplied by 100. Mine read 59072, so my battery has gone through about 590 full charge cycles.<\/p>\n

\"Powershell<\/p>\n

So after 590 cycles, my S24 Ultra battery still holds around 98% of its original capacity.<\/p>\n

Since the battery is designed to retain at least 80% of its original capacity after 2,000 full charge cycles, my battery should be around 94% health. So, it’s performing better than expected.<\/p>\n

Heat seems to matter more than full charges<\/a> for long-term wear, so try not to let your phone run hot for long periods.<\/p>\n

Also, the dumpstate file can include personal details like account names and app activity, so don’t share it. Delete it from your phone and PC after checking your numbers.<\/p>\n

For reference, here’s a guide to the ratings of recent Samsung flagships<\/a> and main competitors based on the European Product Registry for Energy Labelling (EPREL) database: <\/p>\n

Samsung should make battery health available for everyone<\/p>\n

Samsung clearly tracks battery health, and your phone has all the records. So it’s frustrating that the manufacturer won’t make it easily accessible in the settings app.<\/p>\n

If you always wake up to a dead battery, you might want to set up a routine to limit overnight drain<\/a>. <\/p>\n","protected":false},"excerpt":{"rendered":"There are so many things I don’t like about the iPhone: you still can’t download apps outside the…\n","protected":false},"author":2,"featured_media":630944,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[16],"tags":[342,111,139,69,145],"class_list":["post-630943","post","type-post","status-publish","format-standard","has-post-thumbnail","category-mobile","tag-mobile","tag-new-zealand","tag-newzealand","tag-nz","tag-technology"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/630943","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/comments?post=630943"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/630943\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media\/630944"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media?parent=630943"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/categories?post=630943"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/tags?post=630943"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
