Tired of your smartwatch dying before you do? It’s a real problem. You buy this fancy gadget to track your sleep, but you can’t because it’s on the charger next to your bed. Kind of defeats the whole purpose. Everyone thinks you need to drop hundreds of dollars on a big name watch to get good features. But the truth is, the really expensive ones sometimes have the worst battery life. It is a fact that for 2025, the world of cheap smartwatches has gotten seriously good. You can get a watch that lasts for weeks, not hours, and it won’t even make your wallet cry. We’re talking about watches that just keep going.
Why Does Long Battery Life Matter So Much?
It’s all about convenience, really. Who wants another device to charge every single night. You already have your phone, maybe your earbuds. Adding a watch to that nightly ritual is just annoying. A watch that lasts a week, or even two, changes everything.
You can actually use the sleep tracking. This is a big one. The watch stays on your wrist all night, giving you data on your sleep cycles. It’s not sitting on a charging puck.
Then there’s travel. You can go on a weekend trip and not even bother packing the charger. It just makes life simpler, less clutter, less to worry about. It is thought that this freedom from the charger is one of the main reasons people go for these kinds of watches.
Top Budget Smartwatches with Crazy Long Battery for 2025
Okay so let’s get into the good stuff. What watches should you actually look at? The market is flooded with options, but a few brands consistently do a good job with battery for a low price. Normally they use simpler software and screens that dont suck up power.
The King of Stamina: Amazfit Bip 6
Amazfit has basically made a name for itself in this space. The Bip series is famous for its battery. The Bip 6, or whatever they call the next one, is expected to continue this tradition. It’s the one to beat.
It gives you a bright color screen, not like the old dim ones. And the battery? We’re talking two weeks easily with normal use. If you turn some features off you could probably push it to a month. That’s just wild.
Battery: 14-20 days typical use
Screen: Bright and colorful, easy to see outside
Tracking: All the basics are here. Steps, heart rate, sleep, blood oxygen thingy.
GPS: Yes, it has its own GPS which is nice for runs without your phone.
The Minimalist’s Dream: Xiaomi Smart Band 10
Xiaomi’s Smart Bands are less of a full smartwatch and more of a fitness band with a bigger screen. But that’s their secret weapon. By being simpler, the battery life is just incredible. You’ll forget where you put the charger.
This is for the person who just wants notifications, step counting, and time. No app stores, no making calls from your wrist. It’s pure function over flash. And because of that, it’s super cheap and lasts forever.
Battery: 15+ days easily
Screen: A nice vertical AMOLED display
Tracking: Excellent for basic fitness and health monitoring
Price: Generally it costs very little, a real bargain.
The Rugged Option: CMF Watch Pro 2
CMF by Nothing came out of nowhere and made a pretty decent watch. We can guess a second version is coming. They focus on cool design and a simple experience. The battery life on their first one was already good.
A future version would likely keep that focus. A tough build, a big screen, and a battery that can hang with you on a camping trip. It’s a bit more stylish than the others, which some people care about. It has its own special software which is clean and easy to use.
What’s the Catch with These Cheap Watches?
Look, for under $100 you can’t have it all. There are some trade-offs for getting that amazing battery life and low price. It is what it is. You just need to know what you’re giving up before you buy.
You’re not getting a premium feel. The bodies are usually plastic, not titanium or stainless steel. The straps are basic silicone. They feel fine, but they dont feel expensive.
The software can be a bit slow sometimes. Swiping between screens might not be as buttery smooth as on a watch that costs five times more. For most people this is not a big deal.
And the biggest thing is probably the apps. You can’t download third-party apps like Spotify or Strava directly onto the watch. You’re stuck with the apps that come pre-installed. You’ll still get notifications from your phone’s apps, but you can’t run them from the watch itself.
How to Make Your Battery Last Even Longer
Even with these battery champions, you can do things to get even more time between charges. A few small tweaks can add days to your battery life.
First, the screen. Turn down the brightness a little bit. And definitely turn off the always-on display if it has one. That feature is a known battery killer on any watch.
Next, notifications. Do you really need to know every time someone likes your photo on Instagram? Go into the watch’s app on your phone and choose only the most important apps to send alerts. This helps a lot.
Also, continuous heart rate monitoring can be a drain. Most watches let you change the frequency. Setting it to check every 10 or 30 minutes instead of every minute will save a ton of power. It’s a setting you can change pretty easily.

Frequently Asked Questions (FAQ)
Q1: How long should a budget smartwatch battery really last?
A good budget smartwatch in 2025 should give you at least 7 days of battery with normal use. The best ones, like the ones we mentioned, can easily go for 14 days or more. If a cheap watch can’t make it through a full week, you should probably look for a different one.
Q2: Does using the GPS drain the battery super fast?
Yes, absolutely. Using the built-in GPS for tracking a run or a bike ride is one of the most power-hungry things a watch can do. A watch that lasts 14 days might only last 20-25 hours with the GPS running continuously. So just use it when you need it.
Q3: Are these watches waterproof?
Most of them are water-resistant, typically rated at 5ATM. This means you can swim with them in a pool or in the ocean. It’s generally not a good idea to go scuba diving or do high-impact water sports with them, though. Always check the specific rating for the model you buy.
Q4: Can I reply to messages on these budget smartwatches?
Usually, no. You will see the notification for a text message or a WhatsApp message, but you typically cannot type out a full reply. Some might offer a few pre-set “canned” replies like “OK” or “On my way!”, but that’s about it. It’s more about seeing what’s up than having a conversation.
Q5: Is the health tracking on these cheap watches accurate?
For the basics like step counting and general heart rate, they are surprisingly good. They are great for watching trends over time. But, they are not medical devices. For things like blood oxygen or very specific heart rate zone training, their accuracy can be a bit hit-or-miss compared to dedicated medical equipment or a proper chest strap monitor.
